摘要
利用有限元程序计算某城市地铁车站方案设计中双洞式车站和联跨式车站以不同埋深穿越不同地层的情形,对位移和塑性区分布进行比较分析,推荐合理埋深。
In many cases, double - bore station and double - span station will run across different strata with different cover depths coincidentally. After simulating the design of a metro station by using finite element program and making a comparison between the displacement and the distribution of plastic areas, the author argues that reasonable cover depth shall be proposed.
