地铁车站结构抗震设计方法的适用性研究
|
摘要
通过分析各种地下结构抗震设计简化方法的特点,认为其中的反应位移法和反应加速度法比较适合不同埋深、不同土层条件下地下车站结构的抗震设计。针对这两种方法,分别考虑匀质土层和不同土层条件两种情况,均采用一维土层地震反应分析的计算结果,作用于相应的计算模型并进行抗震计算,分析比较结构顶底板的水平位移和内力结果误差以及随结构埋深的变化趋势,从多个方面来探讨两种方法的适用性。结果表明,对匀质土层,两种方法的计算结果变化趋势一致,相对误差小;在上海地区的土层条件下,反应加速度法计算结果的变化趋势比反应位移法较稳定。综合多方面因素,推荐反应加速度法作为地下车站结构的首选抗震设计方法。
By analyzing the characteristics of simplified calculation methods for the seismic design of underground structures, it is suitable to use response displacement method and response acceleration method for seismic design of subway station structures in different depth and different soil conditions. For these two methods, the homogeneous layer and different soil conditions are considered in two cases respectively and the results of soil seismic response is used and act on the corresponding calculation model for seismic calculation. By studying the calculation results of horizontal relative displacement and internal force of underground station, the error and the change regulation are analyzed and compared, the applicability of two methods is discussed from several aspects. The results show that the results of two methods are consistent and the relative error is small for homogeneous soil. According to the change trends of the results, the response acceleration method is more stable than the response displacement method to the Shanghaisoil conditions. In any case, the response acceleration method is recommended as the preferred method for seismic design of underground station.
