摘　　要：地基反力系数是进行地下结构振动分析的关键常数之一。论文改变通常挖去地下结构求地基反力系数的模拟方法,将地下结构纳入有限元模型中进行分析,即考虑结构与地基的相互作用对地基反力系数的影响。在此基础上,对主要影响地基反力系数的边界条件、地下结构弹性模量与地基剪切模量比值以及地下结构埋深等因素进行了参数分析。The stiffness coefficient of foundation is one of the key constants for vibration analysis of underground structures. In this paper, the simulation method of stiffness coefficients of underground structures is changed, and the underground structures are taken into account in the finite element model, that is to say, the interaction between the structure and the foundation is considered.On this basis, the parameter analysis of the boundary conditions, modulus ratio of the modulus of elasticity of underground structure to the ground shear modulus, and its buried depth are carried out.
