| Abstract: | According to the principle of static method and mechanism method of the plastic limit analysis,the linear programming mathmatical models evaluating the upper and lower bounds of limiting loads of arch dam are established.Taking two typical thin arch dams as example,overloading factors and stress state,failure pattern are calculated by use of multi-arch centilever plastic limit analysis method.The ultimate bearing capability and safety reliability of this arch dam are validated. |
