摘要
民用燃气爆炸事故时有发生,砌体结构是民用房屋的一种重要结构形式,其燃气爆炸响应问题仍然不被人们所熟悉。本文针对某砌体居民楼燃气爆炸事故,采用现场踏看、结构检测、结构计算、房屋安全性评定等研究方法,研究了房屋在燃气爆炸后的破坏和响应问题;并采用流体有限元软件,建立了此房屋的三维模型,依据实际情况,数值模拟分析了燃气爆炸过程中的空气温度变化、爆炸冲击波传播及压力变化过程。
Civilian gas explosion accidents have occurred occasionally.Masonry structure is an important structural form of civil housing.However,the problem of gas explosion response is still not familiar with people.In this paper,the problem of damage and response of the house after the gas explosion is studied by the method of field survey,structural inspection,structural calculation and safety assessment of buildings.Meanwhile,according to the actual situation,the air temperature change,the explosion shock wave propagation and the pressure change in the process of gas explosion are simulated and analyzed by using the finite element software of the fluid,and the 3D model of the house is established.
