| 摘 要： | 针对目前备受关注的地下结构内部爆炸问题,在总结国内外研究方法和手段的基础上,以上海市某典型盾构隧道为工程对象建立有限元分析模型,并采用(任意拉格朗日-欧拉算法)ALE算法求解内部爆炸作用下隧道结构及地表土的动力响应方程.通过对计算结果的分析,得出隧道结构及地表距爆源不同位置处的动力响应规律.

| Abstract: | As the problems related to internal blast in underground structures is highly concerned at present,this paper sums up different methods used in research works by both Chinese and foreign scholars.Then,a finite element model is built,according to a typical subway tunnel in Shanghai.The ALE(Arbitrary Langrange-Euler) algorithm is applied to solve the dynamic response equation of the tunnel and ground surface under blast load.The computational result is analysed to get dynamic response laws of different places... |
