Analysis to Evolution of Numerical Simulation to the Whole Process of Destroy for Main Arch of Stone Arch Bridge

6m arch board used as test object, this paper introduces the arch in different level of load board cracks, development and production of plastic hinge until the whole process for all the damage simulation numerical simulation analysis then compared with experimental results and analysis of increased with load crack distribution, which can be used to understand the similar in service work condition of the stone bridge.
