摘要
近年来临水边坡工程越来越多,比如河岸、水库库岸、湖岸等,且这些工程往往结合坡顶房建项目,因此在这些临水边坡设计中不仅要保证边坡安全系数达到规范要求,还要对边坡的沉降、位移值有一个预估,以保证坡顶建筑物的安全。本文结合实际工程,采用MIDAS/GTS有限元软件分析了临水边坡在不利工况下加固前后的安全系数及位移值,并与极限平衡稳定算法的结果进行对比,较好地满足了该类实际工程对沉降及位移需要提前预判的要求,对类似工程的设计具有一定的借鉴意义。
In recent years, more and more near water engineering, such as river, reservoir bank, shore, etc., and these projects are often combined with top of the hill housing construction project, so the design of these waterfront slope not only to ensure safety factor to regulate requirements, but also on the slope of the settlement, displacement of an estimated, in order to ensure the safety of the building top of the hill. This actual project, using MIDAS / GTS finite element analysis of adverse conditions in the reinforcement of the slope near the water before and after the safety factor and the displacement value, and with the limit equilibrium stability of the algorithm results were compared, to better meet the actual construction of the settlement class and displacement to predict in advance the requirements of the design of similar projects with a certain reference.
