［摘要］2004年平遙古城墻南門的局部垮塌,使得平遙古城墻的安全性、可靠性成為人們關(guān)注的焦點。在查明平遙古城墻存在的損傷情況以及分析損傷產(chǎn)生原因的基礎(chǔ)上，針對古城墻可能出現(xiàn)的各種實際工況，建立計算模型進(jìn)行了穩(wěn)定性驗算分析，探討了保證城墻安全性及防止進(jìn)一步損傷的方法，為古城墻的維修加固技術(shù)決策和編制保護(hù)規(guī)劃提供了科學(xué)的依據(jù)。

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.
Keywords:ancient city wall； stability； analysis
