【摘要】 地下结构抗震是当今地震工程界重要的研究方向,目前国内外学者在地下结构横向地震反应领域提出了多种简化计算方法。在有关理论和方法的基础上,对目前常见的地下结构抗震简化计算方法进行了比较详细的介绍,包括地震系数法、自由场变形法、土-结构相互作用系数法、反应位移法、反应加速度法、地下结构Pushover分析方法等简化方法。根据方法的原理,分析各方法采用的简化假设条件以及误差来源,对常见简化方法进行了初步的比较分析。更多还原

【Abstract】 Seismic design and analysis of underground structures have been an important field in earthquake engineering.At present,a variety of simplified calculation methods for seismic analysis of underground structure cross-section are improved around the world.Based on the related theories,a comprehensive comparison of common methods is made,including the seismic coefficient method,the free-field racking deformation method,the soil-structure interaction coefficient method,the response deformation method,the response acceleration method and the Pushover analysis method.Sources of error in these methods are analyzed according to the assumptions adopted by these simplified calculation methods,moreover,these approaches are compared preliminarily.更多还原
