摘要(Abstract)：
利用有限元数值计算方法，借助现代计算机技术，对砖混结构建筑物承重墙爆破拆除预处理进行了计算模拟，并对预处理方案进行了优化设计。提供了承重墙爆破拆除预处理预开拱洞最优形状曲线方程，对承重墙预处理后结构稳定系数进行了优化计算，为工程实践提供了可供参考的计算数据。
In this paper,with the FEM and by the aid of modem computer technique,the calculation simulation of the blasting pretreatment of bearing wall of bricky buildings has been done.The optimum scheme of pretreatment is also selected.The arch hole shape curve formula and the optimum stability coefficient value of blasting pretreatment of bearing wall is provided.Calculation data for reference are provided for engineering practice.
