考虑基础埋深的片筏基础与土的相互作用分析

本文在片筏基础与土的相互作用分析中，考虑了基础埋深的影响，利用Ｍｉｎｄｌｉｎ关于在弹性半空间内作用一集中力，引起的位移场和应力场求解地基的变形，推导了基于Ｍｉｎｄｌｉｎ公式的用角点法求地基变形的递推公式，并编制了相应的有限元计算程序。

Interactive analysis of buried raft foundation and soil medium.

In this paper,Mindlin equation is used to analySis the drsplacement and stress in soil medium cosidering of the effect of buried depth in the interactive analysis of raft foundation and soil,In order to simplify the calculation,the formulas which are used to calculate the settlement based on Mindlin equation have been got.In this paper,raft foundation is divided into bending element.Two soil models,Half-Space and Multilayer have been used in interactive analysis,Based on the principle of interaction between soil and structure,the finite element analysis progrm which can be running on Microcomputer has been coded in PORTRAN-77.In this peper,a typical raft foundstion is illustrated,Some very interesting results which may be useful in practical design are obtained.
