| Abstract: | An effective reinforcement method of abutment anchorage for high arch dam is introduced, and anchoring mechanism of pre stressed tendon is expounded. Then, the arrangement of abutment anchorage of Lijiaxia arch dam is presented. Both the geomechanical model test and nonlinear 3 D finite element analysis for Lijiaxia arch dam with or without abutment anchorage show that abutment anchorage has good reinforeement effect for high arch dam. |
