雨水入渗对某明挖风道边坡稳定性影响分析

Study on the of rainwater infiltration on slope stability of open-cut air duct

在进行地铁明挖风道的施工过程中,为保证施工过程安全顺利地进行,对地铁明挖风道进行地表位移监测。文中引用边坡稳定性分析的经验公式和雨水入渗对边坡影响的计算方法,利用有限元软件进行模拟,并结合现场监测数据进行分析,从而确定雨水入渗引起的风道边坡地表位移变化,对于指导后续工程起到重要作用。

In order to ensure the safety of the construction process smoothly, it needs to monitor the surface displacement of subway open-cut air duct during the construction. By the quoted empirical formula of slope＇s stability analysis and the calculation method which effectes the slope by rainwater infiltration, the finite element software is used to simulate the engineering and analyse the data from monitoring, then determine the surface displacement of air duct slope caused by rainwater infiltration. The research will play an important role in the follow-up project.
