摘要
根据作者提出的考虑变形的朗肯土压力模型 ,对主动土压力折减系数进行了理论上的探讨 ,结果表明 :(1)主动土压力折减系数随内摩擦角的增大而减小 ;(2 )随着位移量的增大 ,主动土压力折减系数也相应的减少 ,并利用离心模型试验的结果进行了验证。
According to Rankine earth pressure model considering deformation presented by the author,the reduced coefficient of an active earth pressure is explored theoretically.The result shows that when the angle of the internal friction decreases or when the displacement of the retaining wall increases,the reduced coefficient of the active earth pressure decreases.In the end,the research results are confirmed by the experiment results of a centrifugal model test.
