| Abstract: | The whole system of elastic_viscoplastic block theory of jointed rock masses is introduced. The methodology is composed of the automatic identification technique, the network seepage analysis method, and the elastic_viscoplastic block theory. Through its application to the Xiaowan arch dam abutment, the deformation and stress distribution as well as the safety factor are obtained. The methodology proposed can be widely used because of its simple preprocessing, high accuracy and its feasibility of dealing with complicated topography and geology. |
