| 摘 要： | 通过模型试验,采用风干砂土实测了绕墙底转动(RBT)位移模式下刚性挡墙土台被动土压力的大小,研究了土台土压力的分布规律以及土台宽度对土压力的影响.与Daly M.P.和Powrie W.(2001)提出的多层楔体试算法结果对比表明:土压力实测值接近于计算值,合力作用点高于计算值,在工程中按多层楔体试算法计算砂土台被动土...

| Abstract: | Passive earth pressures in earth berms against rigid retaining walls in dry sands are modeled in this paper.The passive earth pressures are developed by rotating the retaining wall about a point below the wall base.The earth pressure distributions and the effect of the earth berm width on the magnitude of the earth pressures are studied.The measured earth pressures are compared with the predicted values based on the Multiple Coulomb Wedge Method proposed by Daly M.P.and Powrie W.(2001).It is suggested that ... |
