Abstract:
Soil Investigation work is carried out in geotechnical engineering for the determination of soil properties. Various soil investigation works were carried out in the upstream slope of Pa Bon dam after the movement of upstream slope on July 27, 2014. Bore hole investigation, resistivity test, echo sounding and SASW (Spectral Analysis of Surface Waves) were conducted in the failure zone to determine the failure surface and provide the rehabilitation work accordingly. Likewise, results from piezometer were also used to determine the flow of
water in the failure zone. The investigation work has helped in determining the probable failure surface and rehabilitation work has been proposed accordingly
