Shear strength test on unsaturated soil using natural microscopic surface tension force / Basharudin Abdul Hadi

The shallow infiltration influence slope failure is a complex soil mechanical behavior according to geotechnical engineers. This is because it is very difficult to obtain factor of safety less than unity according to conventional slope stability method for the shallow type of slope failure. The proc...
