ALBERTA TRANSPORTATION PEACE REGION (PEACE RIVER / HIGH LEVEL) INSTRUMENTATION MONITORING RESULTS SPRING 1 SECTION C SITE PH7-1: HWY 9:, DEADWOOD SLIDE 1. OBSERVATIONS 1.1 Field Program and Instrumentation Status Two slope inclinometers (SI15-1 and SI15-) were installed at the Hwy 9: Deadwood Slide site during construction in the fall of 15. The majority of construction work was completed by the end of November 15. The two SIs were read on June 1, 1 by Mr. Niraj Regmi, G.I.T. and Mr. Eddy Mar, E.I.T., both of Thurber Engineering Ltd. The SIs were read using a RST Digital Inclinometer probe with a ft. wheelbase and a RST Pocket PC readout. Inclinometer reading depths were defined as per cable markings with respect to the top of the inclinometer casings.. INTERPRETATION.1 General SI plots with A and B directions are presented in Section D and are summarized below. Where movement has been recorded, the resultant plot (X direction, if applicable) and a rate of movement have also been provided. 17 Roper Road, Edmonton, AB TB 3S5 T: 7 3 1 F: 7 37 715 thurber.ca
. Zones of Movement Zones of new movement were not observed in slope inclinometers SI15-1 and SI15- since the fall of 17 readings. Zones of movement are summarized in Table PH7-1-1 at the end of this report. This table also provides a historical account of the total movement, the depth of movement and the maximum rate of movement that has occurred at this site since the initialization of the slope inclinometers..3 Interpretation of Monitoring Results Slope inclinometer SI15-1 showed a rate of movement of. mm/yr over 5. m to 7. m depth since the fall of 17 readings. SI15- showed a rate of movement of 1. mm/yr over. m to 5. m depth since the fall of 17 readings. Historical groundwater levels recorded in the piezometers are summarized in Tables PH7-1- and PH7-1-3 at the end of this report. All piezometers at this site were damaged prior to or during construction. 3. RECOMMENDATIONS 3.1 Future Work The instruments should be read again during the fall of 1. 3. Instrumentation Repairs No instrumentation repairs are required at this time. Client: Alberta Transportation Date: August, 1 File: 13351 e-file: \\H\13351 rpt PH7-1 - Edm Page of
