摘要
地铁是我国大城市解决交通拥挤问题的有效途经.我国是多震国家,但是对于地铁的抗震研究开展得还很不够.我国还没有制定地下结构的抗震规范,地铁结构抗震计算方法还沿用传统的静力理论,因而不能满足地下工程结构发展的需要.所以,开展对地下结构抗震的深入研究己迫在眉捷.对地铁结构抗震问题进行了综述,着重对于波动力学理论及复杂地下结构系统的动力抗震理论的现状进行了分析,并对未来需要解决的问题提出了建议.
Construction of subway is the effective way to solve the problem of traffic jam in big cities in our country. China is a seismic active country, but aseismic study of subway structures in China is unsufficient. China hasn＇t drawn up aseismic design code, and the design of subway structure is based mainly on traditional static method, which can not meet the need of construction of underground structures at present. Therefore the further thorough aseismic study of subway structures is an urgent work. In this paper a review of this problem is given. The status quo of the wave dynamics method and dynamics method of complex underground structures are analyzed in detail, and the problems in need of further study in the future are proposed.
