施加在土层上的周期性载荷的例子在实际中出现在筒仓或储罐的填充和排空中。这种加载不是动态加载。本文给出了具有随时间循环边界条件的固结方程的一种解。将Ca' Mello筒仓的沉降测量值与正弦加载情况进行了比较。双方就定居点达成了良好的协议。可见土层中心孔压明显大于外加荷载的幅值。
Examples of periodic loads applied on a soil layer appear in practice in the filling and emptying of a silo or a tank. This loading is not dynamic loading. This paper develops a solution to the consolidation equation with boundary conditions that are cyclic with time. Measurements of settlements of the Ca' Mello silo are compared with a case of sinusoidal loading. Good agreement is observed for the settlements. It appears that the pore pressure at the center of the soil layer is significantly larger than the amplitude of the applied load.
