软土路基上的高速公路加宽存在诸多限制因素,在EPS路堤中应用L型挡土墙可以有效压缩边坡占地.解决征地不足问题。由于EPS路堤中土和EPS分层填筑的特点,造成挡土墙的土压力计算与一般均质填土不同。本文通过采取两种计算模式分析此类挡土墙的受力特点,探索计算方法,同时确定EPS路堤中土层厚度。
There are many limitations on widening of expressway on soft soil roadbed, and the application of L-type retaining wall in EPS embankment can effectively reduce the area occupied by the slope and solve the problem of insufficient land acquisition. Due to the characteristics of EPS and embankment in the stratification of EPS, the earth pressure calculation of retaining wall is different from that of general homogeneous filling. In this paper, by adopting two calculation modes to analyze the force characteristics of such retaining walls, the paper explores the calculation method and determines the thickness of the soil in the EPS embankment.
