软土地基复合加筋处治效果对比研究

Comparative Research on the Treatment Effect of Composite Reinforcement of Soft Soil Foundation

为合理确定软土地基最佳处治方案,应用有限元软件计算工后路堤变形和竖向土压力。通过对比分析路堤顶面沉降和路堤水平位移计算结果,认为软土地基采用复合加筋处治后路堤变形量最小,说明复合加筋方案控制路堤变形效果最好。结合路堤竖向土压力计算结果,采用复合加筋处治后地基受到的土压力更小,进一步说明采用复合加筋方案最为合理。

In order to reasonably determine the best treatment scheme for soft soil foundation,the finite element software is used to calculate the deformation of embankment and vertical earth pressure after construction.By comparing and analyzing the calculation results of the top surface settlement of the embankment and the horizontal displacement of the embankment,it is concluded that the deformation of the embankment is the smallest after the treatment of soft soil foundation with composite reinforcement,which shows that the composite reinforcement scheme has the best effect on controlling the deformation of the embankment.In combination with the calculation results of the vertical earth pressure of the embankment,the earth pressure of the foundation is smaller after the treatment with composite reinforcement,which further shows that the composite reinforcement scheme is the most reasonable.
