摘要
为研究不同加筋处治技术在填方地基边坡中的稳定性效应,开展土工格栅加筋以及土工格栅、土工格室组合加筋地基模型试验,对比测试两种技术加固条件下,边坡和地基的应力及变形,并通过理论,分析边坡整体稳定性和坡角局部稳定性。结果表明:组合加筋技术较土工格栅加筋对软基边坡的固结效果提升更佳;加筋效果随着坡体位移的增大而逐渐显现;土工格栅加筋使边坡整体稳定性提升32.4%,组合加筋则可以提高37.8%;土工格室碎石垫层可显著提高坡角局部稳定性。
In order to study the stability effect of different reinforcement treatment technologies in the fill foundation slope,model tests of geogrid reinforced and combined geogrid and geocell reinforced foundation were carried out.The stress and deformation of the slope and foundation are analyzed,and the overall stability of the slope and the local stability of the slope angle are analyzed theoretically.The results show that the combined reinforcement technology improves the consolidation effect of the soft foundation slope better than the geogrid reinforcement;the reinforcement effect gradually appears with the increase of the slope displacement;the geogrid reinforcement makes the slope as a whole The stability is increased by 32.4%,and the combined reinforcement can be increased by 37.8%;the geocell crushed stone cushion can significantly improve the local stability of the slope angle.
