摘要:: 采用当前方法对砖石古塔结构的震害破坏特征进行分析时，构建的砖石古塔有限元模型精度较低，得到的分析结果与实际不符，存在分析结果准确率低的问题。提出砖石古塔结构的震害破坏特征空间模拟分析方法，以小雁塔为例，对砖石古塔结构的震害破坏特征进行分析，确定小雁塔的几何尺寸和材料特性，利用ANSYS分析软件中的solid95实体单元构建小雁塔有限元模型。在小雁塔有限元模型的基础上对砖石古塔结构的震害破坏特征空间进行模拟分析。实验结果表明：所提方法通过构建高精度的小雁塔有限元模型对砖石古塔结构的震害破坏特征进行分析，提高了分析结果的准确率。

Abstract:: When the current method is used to analyze the damage characteristics of the masonry tower structure，the finite element model of the masonry tower is constructed with low precision，and the analysis results are inconsistent with the actual ones，which is low. The spatial simulation analysis method of seismic damage characteristics of masonry tower structure is proposed. Taking Xiaoyan Tower as an example，the damage characteristics of masonry tower structure are analyzed to determine the geometric size and material properties of Xiaoyan Tower. The solid95 solid element in the analysis software is used to construct the small geese finite element model. Based on the finite element model of Xiaoyan Tower，the seismic damage characteristics of the masonry structure are simulated and analyzed. The experimental results show that the proposed method analyzes the seismic damage characteristics of the masonry structure by constructing the high-precision geese finite element model，and improves the accuracy of the analysis results.
