【摘要】 为研究地下结构横断面地震反应分析中常用的反应位移法的实用性,结合子结构法和土-结构动力相互作用法等理论对反应位移法的基本原理进行验证。介绍目前工程应用及规范规程中反应位移法的具体应用形式,对不同计算模型、地基弹簧系数计算方法进行分析。为比较不同形式反应位移法的有效性,以大开地铁车站地震反应为例,将不同形式反应位移法和土-结构动力相互作用法进行对比分析。结果表明,经典反应位移法更接近土-结构动力相互作用法的计算结果,是一个实用性较高的拟静力计算方法。更多还原

【Abstract】 In order to study the applicability of the response deformation method in the seismic analysis of the underground structure,the basic principle is verified by the theoretical analysis based on the substructure method and soil-structure dynamic interaction method.The specific application forms used in engineering applications and design criterions are described.Different computing models and soil spring coefficients were analyzed.In order to verify the efficiency of response deformation method with different forms,the methods of response deformation and soil-structure dynamic interaction are applied to calculate the Dakai subway station structure.The numerical results show that the classic response deformation method is more practical.更多还原
