随着城市地下空间的大规模开发利用,地铁、地下综合管廊、地下商店等地下结构得以大量兴建,其抗震问题已经成为城市地下工程抗震研究的重要组成部分。应用规范推荐的反应位移法对不规则矩形地铁车站结构进行抗震计算,分析不同位移加载方向下结构在设防地震、罕遇地震作用下的内力情况及抗震性能,进一步验证反应位移法的适用性。本文主要通过Abaqus软件对武汉地铁光谷五路站典型截面进行分析。
With the large-scale development and utilization of urban underground space, underground structures such as subway, underground integrated pipe gallery and underground shop can be built in a large amount. The anti-seismic problem has become an important part of earthquake-resistant research of urban underground engineering. The response displacement method proposed by the code is applied to calculate the seismic resistance of the irregular rectangular metro station structure. The internal forces and seismic performance of the structure under fortified earthquake and rare earthquake under different loading directions are analyzed, and the applicability of reaction displacement method is further verified. In this paper, the Abaqus software is used to analyze the typical section of Optics Valley Fifth Station in Wuhan Metro.
