A, Theoretical Analysis of Progressive and Retrogressive Failure in Discontinuous Bock Masses Subjected to 'In-Situ' Shear

Abstract

This paper presents a study of shear deformation which includes a theoretical approach to progressive and retrogressive failure, involving discontinuous and elastic-elatoplastic finite element method. It has been concluded that choice of boundary conditions exertd an important control on failure mechanism. Under certain boundary conditions, the ultimate failure of the test block is a consequence of multiple fracture mode. 'In-situ’ shear tests on geological materials should be interpreted in more sophisticated terms; i.e., as a consequence of variable combined stress state, involving inhomogeneous stress field, one or several of principal stresses being tensile; extensive stress reorientation; and multiple crack propagation. The theoretical approach to the mechanism of shear deformation. The theoretical approach to the mechanism of shear deformation and failure characteristics of 'in-situ' shear tests, utilizing finite element method, appears to be a valid approach for prediction of certain experimental results.
