在Biot饱和多孔介质理论的基础上,应用Laplace变换、Fourier级数展开和Hankel变换将波动方程转化为一组二阶常微分方程;运用薄层法原理在竖向进行离散求解,得到饱和层状地基Lamb问题的Laplace域内解答,并利用Laplace数值逆变换最终得到时域内的数值解答,最后,通过计算实例验证了本文方法.
- Abstract:
-
Based on the Biot saturated porous medium theory, the Laplace transform, Fourier series expansion and Hankel transform are applied to transform the wave equation into a set of second-order ordinary differential equations. The principle of thin layer method is used to solve the discrete solution in the vertical direction, and the Laplace solution of the Lamb problem of saturated layered foundation is obtained, and the numerical solution in the time domain is finally obtained by using the Laplace numerical inverse transformation.
