(北京理正軟件設(shè)計(jì)研究院有限公司,北京100044)[摘要] 較詳細(xì)地介紹了在考慮上部結(jié)構(gòu)、基礎(chǔ)、地基共同作用的基礎(chǔ)分析模型中,形成有限壓縮層分層總和法地基模型的柔度矩陣的原理和方法;并提出了適合于不均勻地層及可局部地基處理的場區(qū)的地基柔度系數(shù),以及對該系數(shù)的修正方法(對應(yīng)力的修正方法)。本文提出的地基剛度模型是考慮共同作用的基礎(chǔ)分析中可優(yōu)先選用的地基模型。

( Beijing Leading Institute of Software Design Co., Ltd. , Beijing 100044 , China)Abstract: This article describes how to build flexibility matrix with unilateral layers wise summation method and introduces flexibility coefficient applicable to uneven ground layers and local area ground treatment and revision methods to ground flexibility coefficient(a stress revision method), which is a preferable interaction approach in soil-foundation-structure analyse.
Keywords: subgrade; foundation design; soil-foundation-structure interaction analyse; foundation model; matrix, unilateral layer wise summation method
