摘　　要：结合西南地区某高速公路斜坡软基高填工点滑塌整治设计实例,提出反压护道结合复合地基、抗滑桩结合复合地基两种方案,从施工、造价、社会影响角度进行对比分析,确定选用抗滑桩结合复合地基方案,并通过三维数值模拟方法对该方案进行评估。采用该方案对路基整治处理后,其沉降变形控制效果显著。Combined with the design example for soft foundation high fill point slump rectification of a highway slope in Southwest China,two schemes of loading berm combined with composite foundation and anti-slide pile combined with composite foundation are proposed.Based on the comparative analysis of construction,cost and social impact,the scheme of anti-slide pile combined with composite foundation is determined,which is evaluated through three-dimensional numerical modeling.The control effect of the settlement deformation of the subgrade is remarkable after this scheme is applied to the treatment of subgrade.
