摘要:
推导了泥石流冲击力作用下结构的最大位移,可以看出最大位移与泥石流的密度、速度,结构的周期、刚度有关。通过对泥石流冲击力的简化,利用有限元软件模拟二层框架结构在泥石流冲击作用下的响应,得到了底层框架柱的位移时程曲线,并对底层柱破坏形态进行了分析。把结构理论最大位移与模拟最大位移进行比较,得到了结构最大位移限值,为建筑物抵抗泥石流冲击设计提供了参考。
Abstract:
This paper deduces structure’s maximal displacement impacted by the debris flow. We can see that the maximum displacement is relevant to the density and velocity of debris flow，the cycle and stiffness of structure. By simplified the impact force of debris flow，using the finite element software to simulate the action of the twostory frame structure impacted by debris flow. The displacement process curve of the bottom of the frame column was obtained and analyze the ground floor column failure form. By compared between structure’s theory maximal displacement and simulation maximal displacement，the limitation of the maximum displacement is obtained. It can provide a design reference for building impacted by debris flow.
