加筋土技术在土石坝滑坡治理中的应用

The Application of Reinforced soil in Landslide Reinforcement of Earth and Rockfill Dams

本文基于土石坝除险加固实际,对加筋土技术在土石坝出险加固中的应用进行探讨。利用ANSYS对某一土石坝现状和加筋状态进行二维有限元模拟,对前后的应力、位移结果进行分析比较。得出加筋在滑体土的中下部时效果最好、加筋层数越多,对坝体的变形控制的越好,但加强的效果逐渐减弱的结论。

Based on the reinforcement situation of earth and rockfill dams,this paper discusses the application of reinforced soil in the reinforcement of earth and rockfill dams.A 2-D finite element analysis to the status and reinforced state of an earth and rockfill dam is performed with ANSYS,and the stress and displacement of the status and reinforced state of an earth and rockfill dam are compared.It is concluded that it is most effective when reinforced in the lower position and that the more reinforcement layers,the little soil deformation,but the effect weak gradually.
