竖向均布荷载作用在土体内部时挡土墙上的附加土压力

Superimposed earth pressure acting on the retaining wall under the effect of verical uniform load in the internal earth

从明德林 (Mindlin)解出发 ,结合朗肯 (Rankine)土压力理论 ,推导了挡土墙后填土内部受竖向局部均布荷载作用时 ,挡土墙上的附加土压力计算公式。较准确地考虑了荷载的作用位置、作用范围和极限平衡状态的影响。

The fomula calculating the superimposed earth pressure acting on the retaining wall under the effect of vertical uniform load,which acts in the internal earth at the back of retaining wall,is obtained in the paper,by making use of Mindlin's solution and scope associating with Rankin's earth pressure theory.The formula considers the acting position and scope of the load,the effect of limit equilibrium condion with relative accuracy.
