Analytical Solution of Transient Matrix Suction for Homogeneous Foundation Under Medium-Peak Rainfall Infiltration
摘要
Abstract
In order to reveal the influence of medium-peak rainfall infiltration on the spatial-temporal distribution of matrix suction,the Gardner soil-water characteristic function is introduced to simplify the Richards transient unsaturated seepage equation and to establish a water transport model for a homo-geneous foundation under medium-peak rainfall infiltration.Fourier integral transform is used to obtain a analytical solution of the transient matric suction during rainwater infiltration under medium-peak rainfall.The analytical solution establishes the mapping relationship between the matric suction of unsat-urated foundation and the rainfall characteristic parameters,which provides a theoretical method for quickly and accurately obtaining the matrix suction and its evolution law at any position of the foundation during the infiltration process of central-peaked pattern.关键词
