摘要
考虑上部结构–基础–地基共同作用下软土地基基础结构的内力分析,判断数值结果是否正确的依据,应使地基反力分布、基础沉降变形的结果均符合基础结构实测规律,且应得到试验和工程实测验证。在初次计算结果的基础上应进行迭代计算,满足输入地基刚度对应的地基反力与计算地基反力的偏差小于10%时,可得到满足工程安全的基础结构计算结果。
The internal force of foundation on soft soils should be gotten by considering upper structure-foundation-soil interaction. The contact pressure and foundation deformation should be in accordance with the measured data, and they should be tested and verified through experiments and engineering practices. Based on the first analysis results, the iterative calculation should be considered. When the deviation of the contact pressure between the input subgrade stiffness and the initial subgrade stiffness is less than 10%, the calculated results of the foundation can meet the requirements of engineering safety.
