软土地区堤防挡土墙地基容许承载力的计算分析

Computation and Analysis of Allowable Bearing Capacity of Foundation for Retaining Wall of Embankment in Soft Soil Area

软土地区堤防存在挡土墙地基容许承载力不足、地基土产生剪切破坏而出现堤防土石体失稳破坏或沿小圆弧滑动情况。分析挡土墙两侧为非对称荷载时的地基容许承载力的计算条件与方法 ,得出近似计算公式 。

For embankment built in soft soil area inadequate allowable bearing capacity of retaining wall foundation will cause shear failure in foundation soil,thus leading to failure or rotational slide of earth_rock mass of embankment.Based on analizing the condition and method for computing the foundation allowable bearing capacity under unsymmetric load for both sides of retaining wall,approximate computation formula is obtained and engineering measures preventing the earth_rock mass of embankment from sliding are put forward.
