    路堤填料改造及其稳定性分析

    ANALYSIS ON STABILITY AND IMPROVEMENT FOR THE LANDFILL OF EMBANKMENT

    • 摘要: 在湖北某高速公路膨胀土路堤设计中,提出三种路堤填料改造方案,并利用Geo-slope软件对路堤进行了稳定性评价。研究表明:加筋对土性参数斜有不同程度的改善作用。土工材料能将上覆荷载有效地分布到更宽的底层路堤,对于防止路堤的不均匀沉降有明显作用。该设计方案对膨胀土路堤是合理、有效的,适宜在膨胀土工程中推广应用。

       

      Abstract: Three kinds of improvement method are put forward in the design of expressway embankment for expan-live soil in Hubei province. It is clear that the value of C and is improved in different extent with inforcement by the analysis of slope stability with the software of Geo-slope. Load on the top of embankment can be transferred to the bottom effectively by the geomaterial,which can mitigate the settlement of embankment remarkably. The three methods are reasonable and effective in improving the expansive embankment and can be applied into engineering of expansive soil in a large scale.
