摘要
通过设计一系列不同宽高比的大方形柔性基础板模型,得到了不同土壤类型、不同宽高比、不同荷载作用下基础底板与地基接触应力的分布。在此基础上提出了底板非线性接触应力分布函数,并分析了荷载工况、土壤类型、基础底板宽高比等因素对接触应力的影响。研究成果可为大尺寸柔性基础的工程应用提供理论和实践参考。
A series of models of large-sized square flexible foundation slabs with various height-width ratios is designed herein,and then the distributions of the contact stress between foundation slab and subsoil under the conditions of various soil types,various depth-width ratios and various loading effects are obtained. On the basis of this,the distribution function of the nonlinear contact stress for the foundation slab is proposed,while the impacts from the factors of the loading condition,soil type,heightwidth ratio of foundation slab,etc. are analyzed as well. The research result can provide theoretical and practical reference for the engineering application of the large-sized flexible foundation.
