Lesson from Instrumented Slope Stabilization Project Using Drilled Shafts
Mechanical and Civil Engineering
A case study of a slope stabilization project using a single row of rock socketed drilled shafts is presented in this paper. The design method, instrumentation program, and slope/drilled shafts monitoring results are presented. The slope is instrumented with inclinometers to obtain soil movement, piezometers to observe the GWT line, and soil pressure cells to measure earth pressures in different zones. Two drilled shafts are instrumented with an inclinometer in each one to measure the shaft deflection. Furthermore, strain gages and pressure cells were also embedded in the drilled shafts to measure the strain in the longitudinal reinforcement and contact earth pressures at the contact interface between the shaft and the soil. Observations and conclusions regarding the effectiveness of drilled shafts in stabilizing the reconstructed roadway embankment are presented.
