Abstract
The undrained shear strength s_u of different tests was found that have great differences in accordance with previous research. What is the type of undrained shear strength tests matches the in-situ condition best. Difference structures and load cause soil forced is difference. Failure surface of soil mechanics behavior that is similar to TC、DSS and TE test. For matching in-situ condition chose undrained shear strength of CAUC、DSS and CAUE tests .
At present, engineering in view of cost and convenience mostly chose undrained shear strength of VST、UU or UC test that have great differences between in-situ condition. The OCR and strain rate are influencing the undrained shear strength ratio factors except difference tests. For undrained shear strength design parameters, probing into undrained shear strength of different tests、OCR and strain rate relationship with undrained shear strength in Various countries.
