人防工程穿墙管线变形破坏计算研究

本文针对核爆炸及常规武器炮、炸弹爆炸破坏作用下,地下人防工程围护结构与周围岩土介质之间存在爆炸震动现象,建立了穿墙管线变形破坏反应的解析解和数值解计算模型。利用上述两种计算模型对算例进行了计算与分析,得出了一些有益的结论,可为人防工程穿墙管线的管材选择、穿墙设计、防护措施及安全评估提供理论指导。

Study for Distortion Destruction of Pipelines through Surrounding Structure of Civil Air Defense Works

Aiming at the shake displacement between surrounding structure for underground civil air defense engineering and the ambient soil under the nuke explosion and the conventional weapon such as cannonball or bomb explosion,the analytical model and the finite element numerical model for the distortion destruction response of the pipelines through surrounding structure are presented in this paper,and these models are applied to example and reach some useful conclusions,which may provide the guidelines for pipe selecting,designs,defending measures and security estimate.
