Cavity expansion in k0 consolidated clay

An elastic-plastic semi-analytical approach is proposed for predicting the cylindrical cavity expansion in K0-consolidated clay. The approach is based on the assumption of small deformation in the elastic region, the K0-based Modified Cam clay (K0−MCC) model is adopted for the K0-consolidated clay, the process of cavity expansion is considered in undrained condition and the semi-analytical approach is obtained by using the similarity technique...
