埋地管线爆炸地冲击作用下解析解计算研究

摘要

The dynamical stress prediction of buried pipelines and its safety analysis is a problem of current research in great demand under conventional weapon underground or ground explosion ground shock waves. For reasons of the complexities and waste time over numerical solution for dynamical stress of buried pipelines under explosion ground shock waves,which is very difficult to deal with engineering designs,the analytic solution method under conventional weapon underground or ground explosion ground shock waves is presented in this paper. This analytic solution method is convenient to use in engineering designs and the analytic results are agreement with the experimental results,which show that it is feasible for this model to apply in engineering designs.%常规武器钻地或地面爆炸地冲击作用下引起埋地管线上的应力如何进行计算是一个值得研究的问题.基于埋地管线爆炸地冲击作用下数值解计算过程复杂耗时,在工程设计应用中不方便,提出了埋地管线爆炸地冲击作用下解析解的计算方法,利用该方法进行计算的结果与实验监测数据较为吻合,表明在工程设计应用中是可行的.
