基于平动模式的刚性挡墙水平位移计算

The rigid retanining wall horizontal displacement calculation according to horizontal moving mode

采用双曲线位移土压力模型,分析了土体与水泥土挡墙之间的非线性相互作用,并假定挡墙为刚体,墙体位移模式简化为平动,提出了一种计算其水平位移的近似方法,通过建立水平方向的平衡方程,解出了挡墙顶部的水平位移,将计算结果与工程实例进行了对比,验证了该方法的合理性。

The paper adopts hyperbolic curve soil pressure model, analyzs the soil block with cement soil wall non-linear interaction, and suppose retaining wall as rigid, the wall moves mode simplification as the horizontal moving, puts forward a kind of approximate calculation move method, passes to establish the horizontal directional equilibrium equation, solving the level horizontal displacement, calculation result and engineering solid a proceeding contrasting, verifying that method rationality.
