摘要
利用积分变换和传递矩阵的方法推导了动荷载作用下路基路面层状弹性体超孔隙水压力轴对称问题的解析解。该方法概念清晰,公式简洁,易于应用。利用Laplace逆变换的数值方法,对层状弹性体的超孔隙水压力进行了分析与研究。
In the paper, an axisymmetric solution is derived for the super-pressure multi-layered elastic body in small opening water on sub-grade and pavement under dynamic load. The concept of the method is clear, and the corresponding formulae are simple and convenient for application. A numerical solution to inverse Laplace transform is successfully introduced in this paper to analyze the super-pressure of the multi-layered elastic body in small opening water.
