大涧河水闸非线性有限元动力响应分析

Big Jianhe Sluice Nonlinear Finite Element Dynamic Response Analysis

水闸是平原区、丘陵区和滨海区应用很广的一种低水头建筑物。但是由于外部环境的影响,尤其是地震对于水闸结构的破坏十分复杂,迫切需要对水闸的地震响应进行科学的研究,以便找出结构的薄弱部位,提出合理建议和加固措施,节省工程投资,避免经济财产的损失。本文采用有限元软件ABAQUS中三维非线性有限元模型,研究在烈度为7度的地震作用下,混凝土材料非线性、地基土材料非线性的动力响应情况。

Summary： Sluice is widely used as a low- head structures in plain area,hilly areas and coastal zones. However,due to the impact of the external environment, especially the destruction of the earthquake for the sluice structure is very complicated,the urgent need scientific researching for seismic response of sluices,in order to identify weak parts of the structure,put forward reasonable proposals and reinforcement measures,saving investment,to avoid economic loss of property. In this paper,three- dimensional finite element software ABAQUS finite element model to study the seismic intensity of 7 degrees under the effect of material nonlinearity of concrete,foundation soil nonlinear dynamic response of materials.
