pseudo-static coefficient

Recommendation required
Hi folks: I am involved a project dealing with slope stabilization. The height of slope is about 106 ft, the angle is about 36. The upper 65 ft thick layer is primary composed of SP, and the lower layer is CL-ML. The friction angle of SP and CL-ML is 33, 30 respectively, allmost cohesionless for...- wshi

How to determine the friction angle
Hello all: I am involed a site invesigation project in which I will have to determine the bearing capacity and friction angle of the soil. The tests we have performed included seive analysis,atterberg limits tests and SPT. These soils are silty sand or silty gravels. According to these three...- wshi
