轻质填料置换治理类软土地基高路堤滑动变形研究

Study on High Embankment Sliding Deformation of Quasi-soft Foundation Treated by Replacing with Light-weight Fill

从治理方案选择、轻质路堤设计及施工关键技术等方面,详细介绍轻质填料置换法治理类软土地基高路堤滑坡的工程实例。比较规范法和荷载法计算轻质路堤整体稳定性,给出路堤滑坡处治前后的深层位移监测成果,认为采用荷载法更为合理,并论证了治理方案的可行性。

Herein the engineering example of how to treat high embankment slide of quasi-soft foundation by replacing with lightweight fill was introduced from the aspects of the scheme selection and the design and construction techniques of lightweight embankment. The stability of the lightweight embankment calculated on the basis of specification and by the loading method was compared,the results of deep displacement monitoring before and after the treatment of embankment slide were provided.It was considered that the loading method is more reasonable and it proves the feasibility of the treatment scheme.
