Modelling of shear characteristics at the concrete–rock mass interface

An analysis of shear characteristics on the concrete–rock mass interface is presented, in order to simulate the effect of load at the contact of concrete structure of the dam and the rock foundation. The analysis is based on the real mechanism of shear, which is different from the so-called the “saw tooth” model that simulate the walls of joints in the rock mass. As a result, the analytic form of shear deformation and shear strength as a...
