本文利用二维线性动力有限元方法分析了核爆炸压力作用下,作用在土中浅埋刚性结构上的相互作用荷载及其与结构、土壤的几个主要参数之间的关系。并从工程使用的观点,讨论了实际存在于土中的二维受力状态当用一维波理论进行分析时可能存在的误差情况。
In this paper, two-dimensional linear dynamic finite element method is used to analyze the relationship between the interaction load acting on shallow rigid structures in soil and its relationship with several main parameters of soil under the action of nuclear explosion pressure. From the point of view of engineering use, the possible errors in the analysis of the two-dimensional stress state actually existing in soil when using one-dimensional wave theory are discussed.
