为了研究不同破坏类型夯土长城在地震作用下的动力响应特征,以山丹明长城为研究对象,选取典型的破坏类型,通过有限元软件MIDAS/GTS建立了同种物理参数和几何尺寸的完整长城模型、基础掏蚀长城模型和人为挖洞长城模型,对3种不同类型的夯土长城模型输入山丹6.1级地震加速度时程.结果表明完整长城最大应力位于长城底部,结构有破坏的长城最大应力位于结构破损处,3种墙体的加速度和位移大体上随高度增加而增大,但结构有破损的长城其加速度与位移在特定位置增长规律有所不同,且结构有破损的长城应力、位移与加速度相比于完整长城都有所增加.

英文摘要：

In order to study the seismic dynamic response of the Great Wall, a typical type of the Great Wall made in Shandan in Ming Dynasty were selected in this paper. Based on finite element software, the models of the complete wall, the wall with blow-out base, the wall with man-made destruction were built respectively and studied by inputting Shandan 6.1 magnitude seismic wave. The results of this study are summarized as follows： the maximum stress of the complete Great Wall is located at the bottom of the wall; the maximum stress of the structure damaged wails is located at structure damage position, the seismic acceleration and displacement of different types of the Great Wall increase with the rise of altitude. But the acceleration and displacement of structure damaged wall have different growth rules at special position. The maximum stress, peak acceleration and peak displacement of two damaged Great Wall are greater than the complete wall.
