17 INTRODUCTION To provide guidance notes to design engineers on practical aspect of : Subsurface Investigation (S.I.) and Specifying of Laboratory Tests For Geotechnical Design of Hill-Site Development or Cut Slopes: Planning of Subsurface Investigation 1. Introduction 2. Desk Study 3. Site Reconnaissance 4. Extent of S.I. 5. Selection of Types of Field Tests & Sampling Methods. + Determining of Groundwater
18
19 Planning of Subsurface Investigation Usually Two(2) Stages S.I. : (1) Preliminary S.I. - To obtain general subsoil profile. - Preliminary planning of layout or formation level. - Preliminary soil parameters & water levels - Preliminary design & (cost + time) estimates. (2) Detailed S.I. - Plan for critical areas of concern (e.g. major fill or cut, valley which has soft materials) - Refine soil parameters for detailed design. - Locations with structures (e.g. walls, foundations) DESK STUDY Geological Maps & Memoirs Topographic Map Aerial Photographs Site Histories Details of Adjacent Development Requirements of the Proposed Structures or Foundations
20 Aerial Photographs Development History of Site Aerial Photograph (22 years ago) Proposed Development
21 Aerial Photograph (18 years ago) Proposed Development Aerial Photograph (4 years ago) Residential Residential Proposed Development Residential
22 General Geology Hawthornden Schist Formation SITE LOCATION Sg. Klang Bukit Antarabangsa Granite Kuala Lumpur Limestone Source: Geological Map of Selangor, Sheet 94 Kuala Lumpur, 1976 SITE RECONNAISSANCE Confirm & obtain additional information of site Examine adjacent and nearby development Compare surface features and topography with data obtained from desk study (e.g. Vegetation) Locate & study the outcrops, previous slips
23 EXTENT of S.I. Depends on : - Available Information - Geological Formation & Features - Variability of Subsoil & Groundwater - Proposed Structures & Foundations S.I. In Grid Pattern (Wrong!!) (Total = 32 nos)
24 Proposed SI (Correct Way) To Place boreholes across the slopes cross - sections. To get subsoil profile for analysis and design (Total = 32 nos) Depth of Field Tests for Slopes Design
25
26 Selection of Types of Field Tests & Sampling Methods. + Determining of Groundwater
27 Selection of Types of Field Tests Commonly used Field Testing for Hill-Site development : * Boreholes - Standard Penetration Test (SPT) - Collection of disturbed & undisturbed soil samples. - Collect rock Samples & Sampling Methods - Used in long term as Standpipe (Groundwater Monitoring) (A) Light Dynamic Penetrometer (JKR or Mackintosh Probes) - determine soft layer or shallow rock Boreholes Described in BH5930:1981: - Borehole includes : boring, sampling, in-situ testing and indicative water table observation. - Depth usually < 100m - Drill through all soils & core through rocks Type of Drilling : Rotary drilling by circulating fluid (water or bentonite or air foam) is most common. Wash boring percussive action (chisel) Lots of disturbances
28 Rotary Drilling Rig
29
30 Standard Penetration Test Standard Penetration Tests (SPT) BS Obtained SPT N values (blowcounts per 300mm) - Usually carried out at 1.5m depth interval. - At greater depth can use larger interval. - Obtained disturbed soil samples from split spoon sampler. Split Spoon Sampler of SPT
31 Collection of Soil Samples from Borehole Types of Soil Samples : - Wash Samples :- from soil washed out from the borehole for soil strata description. - Disturbed Soil Samples :- from split spoon samplers after SPT. - Undisturbed Soil Samples :- (a) (b) (c) Piston Sampler (very soft clay) Thin Wall Sampler (soft soils) Mazier Sampler (Commonly used for SI in Hill-Site as can collect UD soil samples in residual soils or stiff soils) Note : Require STABLE PLATFORM Mazier Sampler / Triple Tube Core Barrels -Contain detachable liners within the inner barrel. -Ideal for triaxial test as the diameter of core is 74mm. -To sample undisturbed soil samples from Stiffer soil stratum.
32 (a) Determination of Groundwater Groundwater affect Effective Stress of the Soil Borehole (temporary & indicative) - Daily observation of water level in the borehole. (indicative only). - Prevent surface water flowing into the borehole. (b) Standpipe or Piezometer (long term & representative) - Porous elements must be fully saturated & filled with deaired water or glycerine fluid. - For quick response use Vibrating wire piezometer Standpipe & Open Hydraulic Piezometers
33 Boreholes with Standpipe Piezometers Lockable Cap to prevent vandalism Bright Color (Red + White) to prevent vehicle knocking into it. Borehole Number Clearly Marked on Concrete Interpretation of Laboratory Tests TWO Major Categories : (1) Strength Parameters : - Stability Analyses of Slopes & Embankment. - Bearing Capacity Analyses for Foundation. (2) Stiffness & Deformation Parameters : Prediction & evaluation of :-: Settlement, Heave, Lateral deformation, Volume Change.
34 Strength Parameters TWO Conditions : (A) Total Stress : - For Short Term Conditions in Cohesive Soils. - Little of no drainage. (B) Effective Stress : (Commonly used for Cut Slopes Analysis) - For Long Term & Permanent Conditions. - Fully Drained Conditions. (i) (ii) Effective Stress Strength Parameters c & φ Interpretation from Isotropic Consolidated Undrained Triaxial Test, CIU + ΔU Isotropic Consolidated Drained Triaxial Test, CID (iii) Laboratory Shear Box Test (at very. slow rate)
