摘　　要：砖石古塔在我国古塔中历史最为悠久,在现存古建筑中体型最为高大,保存数量最多,具有重要的研究意义。以南京牛首山弘觉寺塔为研究对象,利用部分实测数据以及材性指标,应用有限元分析软件ANSYS对楼阁式古塔特有的错角结构与一般楼阁式直筒结构性能进行了对比。研究发现两种结构的动力特性及荷载作用下的结构性能相似,但错角筒结构能避免不均匀沉降引起的应力集中。Masonry pagodas in China with a large gradient and quantity, have important research significance. This dissertation selects a research object,Hongjuesi pagoda in Nanjing city,to make a contrast between turn structure and empty-tube structure. During the process of modeling, we use the data measured by Nanjing institute of Engineering and Architecture and indexes in standard. By using finite-element. By using finite- element analysis software ANSYS, we studied different mechanical properties of the two structures under different loads. The research shows that the two structures do not have much difference under various loads, but turn structure avoids stress concentration under uneven settlement.
