摘　　要：通过玉蒙铁路膨胀土路堤桩板式挡土墙离心模型试验,就路堤加筋、不加筋两种工况,以及最优含水量及富水两种含水条件进行模拟测试。试验结果得出,弱膨胀土路基加筋的作用效果十分明显,使路基的变形得到了有效控制,满足了设计要求。弱膨胀土含水量的变化对路基的变形有明显影响。Through centrifugal model test on sheet pile retaining wall for expansive soil embankment in Yumeng Railway,simulation test is carried out on reinforced embankment and unreinforced embankment,the optimum water content and rich water content.It is known from result that reinforcement for weak expansive soil embankment has significant effect,which effectively controls embankment deformation and satisfies design requirement.The changes of water content in weak expansive soil have great influence on embankment deformation.
