Research Abstract

In this research project we have derived the strength parameters to be obtained from various kind of laboratory and field tests on clay. The basic idea is in the development of an elastic-viscoplastic constitutive model of incremental type. Especially we have paid attention in analysing the strength parameters to be obtained from the constant-volume-shear-boxtests and the field vane tests both of which are relatively inexpensive and yet are not widely used the in engineering practice for a reason that their theoretical backgrounds are not well-established. In addition to the purely theretical derivation of the strength parameters, we have developed computer programs to simulate the 3-dimensional soil/water coupling problems associated with the failure of clay. This FEM program requires a super-computer to solve the problems. By using the FEM program developed for 3-D soil/water coupling problems based on an elasto-viscoplastic constitutive model, constant-volume-shear-box tests and field vane tests are successfully simulated. The results are in good accordance with the tests on various kind of clays collected from over this country.
