摘要
万万高速公路南段路基在雨季长期处于浸水状态,如何提高浸水路堤的长期稳定性是亟待解决的工程问题。本文针对桩网纵向加筋对浸水路堤稳定性的影响展开研究,研究采用FLAC3d软件构建浸水路堤的三维数值仿真模型,针对浸水路堤桩网加固的不同参数(桩间距、桩长等)对路堤的变形特性、承载能力及荷载传递特性等的影响进行研究,研究结论可应用于指导桩网加固浸水路堤的设计与施工。
The subgrade of the southern section of Wanxiang-Wanrong Expressway has been flooded for a long time in the rainy season.How to improve the long-term stability of flooded embankment is an engineering problem that needs to be solved urgently.In this paper,the influence of longitudinal reinforcement of pile network on the stability of flooded embankments is carried out.The research uses FLAC3d software to build a three-dimensional numerical simulation model of flooded embankments.The effects of deformation characteristics,bearing capacity and load transfer characteristics are studied,and the research conclusions can be used to guide the design and construction of pile network to strengthen flooded embankments.
