【摘要】 反应位移法是地下结构抗震分析中常用的方法。针对经典反应位移法存在的问题与计算误差,对三个方面进行了改进。一是对地基弹簧的改进;二是对地层剪力计算的改进;三是同时对地基弹簧和地层剪力计算进行改进。从而提高了反应位移法的计算精度及其计算效率。更多还原

【Abstract】 The response deformation method is commonly used for seismic analysis of underground structures.There are three aspects which can be improved for the problems and errors in calculation of the classic response deformation method.One for foundation spring,one for the calculation of stratigraphic shear-force,and the another for both foundation spring and the calculation of stratigraphic shear-force.So the precision and efficiency of calculation of response deformation method are improved.更多还原
