Abstract:Pingyao ancient city wall, which was built 600 years ago, had been preserved well and was in a good condition. However, after a recent local collapse near its south gate happened in 2004, the safety and stability of the wall arised great concerns.  A method is proposed to prevent the city wall from further damage and keep its safety. After investigations on the existing damage and the reasons, a computational model is established. Then, numerical calculations with several well designed cases have been done to mimic real situations. The proposed method not only can serve the maintenance work on such old buildings, but also can help on the compiling the protection codes and regulations.
