【提要】 根據(jù)地基與基礎(chǔ)的共同作用分析原理，采用SFIA系統(tǒng)，通過對(duì)中關(guān)村科技大廈的變形分析，較好地預(yù)測了建筑物的沉降、差異沉降、基礎(chǔ)內(nèi)力的特征及其分布規(guī)律。在此基礎(chǔ)上，根據(jù)分析建議，設(shè)計(jì)從多方面采取先進(jìn)而有效的結(jié)構(gòu)措施調(diào)節(jié)建筑物的差異沉降和基礎(chǔ)內(nèi)力分布，從而確保了天然地基方案實(shí)施的安全和經(jīng)濟(jì)，并為施工措施的優(yōu)化提供了可靠的保證。
【關(guān)鍵詞】 高層建筑物 群樓 地基 基礎(chǔ) 差異沉降 剛度 結(jié)構(gòu)分析 共同作用
Subsoil and Foundation Interaction Analysis of Zhongguancun Science & Trade Center/Han Xuan１,Tang Jianhua１,Xiang Xianzhou２,Yu Wei１,Wang Huaizhi2(1 Beijing Geotechnical Institute,Beijing 100038,China; 2 Beijing Architectural Design Institute of CSCEC,Beijing 100073,China)
Abstract:Based on the theory of subsoil and foundation interaction analysis,the SFIA soft,developed by the Beijing Geotechnical Institute,has been employed to calculate the settlement of a highrise building of Zhongguancun Science & Trade Center.The influences of the nonlinear behavior of the ground soil,multiple construction phases and structural tiffness have been considered.The distribution of the total settlement,differential settlement,inner force of the foundation of this structure have been predicted successfully,and some suggestions on the methods to adjust and control the differential settlement and inner force of the foundation have been made to the designer based on SFIA analysis.So that a safe and economical foundation design and an optimized construction scheme have been guaranteed for this important building.
