The Application of Discrete Element Method in the Analysis of Stone Arch Bridge

Demonstrate the feasibility of the discrete element method application in the stone arch bridge analysis. Put forward simulation and analysis methods of stone arch bridge with fracture and damage. Using UDEC two-dimensional discrete element analysis software to establish arch bridge model, establish a load test state and simulate the overload test, make a force and damage identification via analyzing the main bearing structure arch ring. Discrete element model calculation result has good consistency with the actually measured value. Using the discrete element method can be effectively considered discrete problems of masonry materials, and accurate simulate the discrete characteristics of arch bridge structure materials.
