Deformation Control and Its Countermeasure of Embankment Slope in Deep and Thick Soft Foundation

In combination with a deep soft soil embankment slope engineering instances,the reinforced soil retaining wall was proposed to support the slope.The stability and deformation of the reinforced soil retaining wall was analyzed by using the finite element analysis methods.Then the work characteristics of reinforced soil retaining wall and the countermeasures to avoid deformation were discussed.The results show that the reinforced soil retaining wall which have low requirement of bearing capacity and uneven settlement deformation can be used to soft soil foundation.CFG pile can transfer the upper structure load to the deep soil,which can effectively improve the bearing capacity and control the settlement of the foundation.Under the condition of soft soil foundation,the reinforced soil retaining wall should be preferred.Research results can provide guidance for similar slope engineering design.
