地下结构横截面地震反应拟静力计算方法对比研究
|
摘要
对目前地下结构横截面地震反应计算中广泛采用的地震系数法、自由场变形法、土-结构相互作用系数法、反应位移法、反应加速度法等多种拟静力方法进行介绍及分析。以大开地铁车站地震反应为例进行数值模拟,通过改变输入地震波、结构刚度、土层刚度以及结构埋深对各种拟静力计算方法的适用性进行了研究,将不同方法的计算结果与动力时程分析方法结果进行了对比。研究结果表明:反应加速度法与动力时程分析方法符合较好,表明该方法在常见地下结构环境条件下具有良好的适用性与计算精度,可以用于地下结构的抗震反应分析。
The widely used pseudo-static methods for the seismic analysis of an underground structure are introduced,such as the seismic coefficient method,the free-field racking deformation method,the soil-structure interaction coefficient method,the response deformation method and the response acceleration method.Based on the Daikai subway station,a study on applicability of the methods is carried out by changing the input earthquake waves,the stiffness of a structure,the stiffness of soil and the burial depth of a structure.And the results obtained through the methods are compared with those obtained through the dynamic analysis method.The comparison shows that the results obtained through the response acceleration method and the dynamic analysis method are in a good agreement.Thusly it is indicated that the response acceleration method has a high applicability and good computational accuracy and is suitable for the seismic analysis and design of underground structures.
