摘要
以弹性理论为基础 ,从不同角度提出了建筑物塌落体触地最大冲击力的三种计算方法 ,三种方法计算结果吻合好 ,均认为最大冲击力Pmax主要与塌落体和地表土体的力学参数、塌落体质量、形状及下落高度等因素有关方法 3根据塌落体不同形状可以得到不同的Pmax,具有广泛适应性 。
Based on elastic theory,three kinds of calculating methods of the maximum impulsive force ( P max ) that collapse building shocks surficial soil are put forward in different views, and their results are consistent well. P max is related to the mechanical parameters of collapse building and surficial soil, and the mass, the shape and the falling height of collapse building. The method 3 has wider adaptation advantage because of its character that different P max corresponds different shape of collapse building. These studies are expected to supply theoretical basis for calculating P max and protecting in practice.
