摘要

半空间点源问题的结果积分往往不能表达为有限形式，经济上未必可行，且不便于工程应用。如与数值法结合，将区域?适当分割并变换为特定的形式，则可降低积分重数，甚至得到解析解。本文将讨论以解析解为基础辅以数值法的近似积分方法，并将其应用于改进扎列茨基解，进而求解三相土的固结沉降问题，并进行参数敏感性分析，得出渗透系数、泊松比以及模量比对固结沉降均有较大的影响；另外该近似解能够较好的求解三相土固结沉降，具有一定的应用价值。

Abstract

Normally

it is difficult to get the satisfied integration result of the half-space. If it is bonded with the numerical method

the continuum may be gotten. In the paper

the equiareal isometric transformation of the domain area is made. Furthermore

it is applied to the consolidation settlement in the three-phase soil

which is studied based on the Зарецкий Ю. К. Solution. Moreover

the sensitivity of the parameters

such as seepage coefficient

modular ratio and the Poisson’s ratio

are analyzed. Some worthy solutions are presented.
