Analysis of soil classified samples as typical for site area type C (industrial area, mining area, communication areas). 5. Characterization of geotechnical conditions for the foundation 5.1 Soil-water conditions The area of the test is located on the flat glacial moraine eminence and partially also peat plain in the Odra valley. The ground surface is on the level between 11,4 m to 20,7 m over sea level +10 m. On the basis of the boreholes (see App. 4.0) in the basement exist mainly Pleistocene, glacial fine deposits and non-cohesive fluvioglacial deposits. In few cases close to the surface man made deposits exist with the thickness not more than 2,0 m (except area of the borehole BH 402, BH 403 and BH 406 were its thickness is up to 2,8; 4,5 and 3,5 m; additionally in CPTU 423 to depth 3,6m). Organic deposits were recognized in the borehole BH 407 (up to depth of 5,0 m), BH 414 (up to depth of 9

10 3,5 m), BH 417 (up to depth of 12,5 m), BH 418 (up to depth of 13,2 m), BH 419 (up to depth of 12,0 m), BH 420 (up to depth of 16,5 m) and BH 421 (up to depth of 12,5 m). Additionally organic deposits were interpreted in CPTU test no. 423 (up to depth of 3,6 m), 425 (up to depth of 3,3 m), 430 (up to depth of 10,2 m), 431 (up to depth of 10,6 m), 434 (up to depth of 11,9 m) and 437 (up to depth of 10,0 m). On the basis of performed boreholes two hydrogeological layers were discovered: On the moraine eminence - first layer located close to the surface, in the sandy deposits it is suspended on the clay layer, water level is on the depth 0,2 3,0 m, elevation about 15,5 18,3 m over sea level +10 m; water level horizon is free or slightly under pressure; water level tides could reach 0,5 m from actual level, especially after heavy rains or thaw; - second layer is connected with fluvioglacial deposits located under and between boulder clay; water level horizon is under pressure and stabilized on depth 4,2 7,1 m, elevation about 12,0 14,2 m over sea level +10 m. On the peat plain There is one large water horizon which is in the hydraulic contact with river Odra. Water level is on the depth 1,2 3,5 m, elevation about 8,3 12,1 m over sea level +10 m; water level horizon is free; water level tides could reach 1,0 1,5 m from actual level, especially during flood periods. During a period of 2 weeks the water level measurements in piezometers where done. In these period water level changes reach up to 0,1m. On the area of the Site I and III there are simple soil conditions except boreholes BH 402, BH 403, BH 405, BH 406 and CPTU 318, 319, 423 where soil conditions are complex. Also in hole river valley there are complex soil conditions (according to Regulation [58]). 5.2 Geotechnical layers characteristic In the basement of the Site I, III and partially IV there are mostly strong soils which have which have similar physical (type and consistency) and mechanical (strength and modulus) properties. Soft soil layers (IA, IB, IIA, IIB and IIIA) lay mainly close to the surface or makes interbeddings in the upper part of soil profile. Only between boreholes BH 402 and BH 406 there is deep man made layer. On the peat plain soil conditions are poor because of few meters peat layer existing and not deep water horizon. As a criterion to divide soil into the layers it was taken into account: - type of soil according to its granulometry it is highlighted by numbers I to III; 10

11 - age and genesis according to granulometry, petrography, soil profile, color; - state of the soil density and consistency which are described on the basis of CPTU test, SPT test, correlation with lab test. Comparison of the characteristic geotechnical parameters shows App. 10. Strength parameters where described on the basis in-situ and laboratory tests: - effective friction angle for corse material CPTU test; - effective friction angle for fine material triaxial test CU, CD and direct shear apparatus; - effective cohesion triaxial test CU, CD and direct shear apparatus; - shear resistance CPTU test and correlation with triaxial UU test. Some big differences in the presented outcomes are connected with high amount of corse fraction in cohesive soil like gravel and cobbles. It gives big range of density outcomes in layer IIIC and high strength laboratory parameters for layer IIC. There are given ranges of outcomes with recommended values in the table of parameters. Coefficient of permeability was extracted from granulometry analysis by empirical formulas (USBSC) for corse material and also in the trial pits by the Lefranc method. There are main geotechnical layers: a) Geotechnical layer IA Man Made deposits - uncontrolled. Made by sand, silt and clay with rubble. b) Geotechnical layer IB Organic deposits with high amount of organic mater. Undrained shear strength c u = 0,002 0,02 MPa. Soft soil genesis of deposits. a) Geotechnical layer IIA This deposits are represented by fine material sacl. Consistency of the soil is soft, liquidity index I L = 0,50 0,70. Glacial genesis of deposits. a) Geotechnical layer IIB This deposits are represented by fine material clsi, clsa, sacl, Si. Consistency of the soil is firm, liquidity index I L = 0,25 0,40. Glacial genesis of deposits. a) Geotechnical layer IIC This deposits are represented by fine material clsa, clsi, sacl, sasi, Si, sicl. Consistency of the soil is stiff and very stiff, liquidity index I L = <0,00 0,20. Glacial genesis of deposits. 11

Fluvioglacial and alluvial genesis of deposits. a) Geotechnical layer IIIB This deposits are represented by corse material MSa, FSa, sisa. State of the soil is medium dense, density index I D = 0,35 0,65. Fluvioglacial and alluvial genesis of deposits. a) Geotechnical layer IIIC This deposits are represented by corse material Bo, Gr, CSa, MSa, FSa, sisa. State of the soil is dense and very dense, density index I D = 0,70 0,80. Fluvioglacial and alluvial genesis of deposits. 5.3 Soil properties according to foundation use Soil strong geotechnical layers IIC, IIIB and IIIC are useful for foundation. Soft soil layers IA, IB, IIA, IIB and IIIA are not useful as they are they need improvement or exchange. All soil works should be done under geotechnical supervision. All changes in the model should be reported to the designers. For the strong layers it is recommended to make analysis of direct foundation. To protect against differential settlements it is better to locate foundation in the homogenous geotechnical layers. For high loads and pile foundation it is recommended to use for design soil resistance according to CPTU test. 6. Summary and remarks 1. The investigation is located on the glacial moraine eminence and partially peat plain. Design object is classified to third geotechnical category. On investment area on the glacial moraine eminence there are simple soil conditions except boreholes BH 402, BH 403, BH 405, BH 406 and CPTU tests no. 318, 319, 423 where soil conditions are complex. Also in hole river valley there are complicated soil conditions. 2. In the geotechnical profiles there are mainly fine glacial deposits with interbeddings of corse and very corse material and also soft soil. Man made deposits on the depth of 2 m are located only in the area of points BH 402, BH 403, BH 405, BH 406, CPTU 423. On the peat plain organic and man made deposits are in points : BH 407, BH 414, BH 417, BH 418, BH 419, BH 420, BH 421, CPTU 423, 425, 430, 431, 434, 435, 436,

13 3. In the area there are three main geotechnical layers. In basement there are hard, bearing geotechnical layers IIC, IIIB, IIIC (useful for the construction) and soft soil layers IA, IB, IIA, IIB, IIIA (unsuitable for construction) which should be removed or improved. 4. During the test there were discover two water bearing horizons. Hydrogeological conditions of the study area vary within the moraine eminence and the river valley. One on the moraine eminence: - first layer located close to the surface, in the sandy deposits it is suspended on the clay layer, water level is on the depth 0,2 3,0 m, elevation about 15,5 18,3 m over sea level +10 m; water level horizon is free or slightly under pressure; water level tides could reach 0,5 m from actual level, especially after heavy rains or thaw. - second layer is connected with fluvioglacial deposits located under and between boulder clay; water level horizon is under pressure and stabilized on depth 4,2 7,1 m, elevation about 12,0 14,2 m over sea level +10 m. On the peat plain there is only one large water horizon which is in the hydraulic contact with river Odra. Water level is on the depth 1,2 3,5 m, elevation about 8,3 12,1 m over sea level +10 m; water level horizon is free; water level tides could reach 1,0 1,5 m from actual level, especially during flood periods. 5. Soil in the excavation should be protected form longtime influence of the unfavorable atmospheric conditions (heavy rains, thaw) or frost effect not to worse their mechanical parameters. 6. All spade works should be done under geotechnical supervisor. All changes in the presented model of the basement should be reported to the design team. 13
