摘要:
土工格栅加筋柔性支护技术已成功治理南方多处膨胀土坍滑边坡。为验证柔性支护技术在北方深路堑边坡的处治效果,采用FLAC 对北京膨胀岩(土)深路堑边坡柔性支护前后的位移、应力应变以及边坡稳定系数进行对比分析。研究表明:经干湿循环后,相比素膨胀土边坡,土工格栅加筋柔性支护的膨胀土堑坡发生的位移要小,坡脚处的剪应力集中减小,坡体没出现明显的剪切带,边坡整体稳定。
Abstract:
The technology of geogrid reinforced flexible supporting has been successfully managed several the southern expansive soilslumping slope. To verify the effect of the flexible support technology in treating the northern deep cutting slope, the author compared thedisplacement, stress and strain , and slope stability coefficient of Beijing expansive rock (soil) deep cutting slope between flexible supportedand undo based on FLAC. The studies showed that the displacement of expansive soil cutting slope by geogrid reinforced flexiblesupporting smaller than the unreinforced expansive soil slope, so did the shear stress at the toe, otherwise the slope didn’t appear apparentshear zone and was overall stable after wetting-drying cycles.
