【摘要】 对于软土浅埋隧道,由于其所处地质条件复杂,因而对于其开挖稳定性分析一直是一个难点。阐述了如何应用有限元法对施工过程进行动态模拟,和在模拟中所遵循的原则,应注意的问题等,最后用工程实例加以说明。更多还原

【Abstract】 It is all along difficult to analyse its stability due to complexity geology condition for the shallow soft-soil tunnels. This paper expatiates how to use the finite elements method to simulate the construction process. In addition , the author points out what principles should be followed, and what problems should be paid attention to. At last, the author set a example to explain it.更多还原
