【摘要】 主要研究岩石地基上高层建筑条形基础的计算模型和参数取值,提出文克尔地基模型为计算这类基础的适用模型,阐述了岩石地基上基床系数的特点,给出用岩石天然状态下的单轴抗压强度换算基床系数的回归公式,最后分析了基础结构在这种模型下的内力特征,并用一个工程算例说明了本文的方法,可供地基基础设计参考。更多还原

【Abstract】 In this paper,the design method of strap footing of high-rise building on rock subgrade is researched.The Winkler model is applied as a perfect model to calculate this kind of foundations.The regressive formulas to estimate the subgrade coefficient are provided.The method is proved to be applicable by an actual engineering example and can serve as reference to the civil engineering designers.更多还原
