摘要
通过分析求解不同基床系数的计算方法,得到由Biot和Vesic两种方法计算的基床系数不仅在数值上存在很大的差异,而且基床系数-基础宽度、基床系数-基础厚度、基床系数-地基土的泊松比关系曲线的变化趋势上,两者也存在差别。根据建筑使用功能、建筑场地类别建立了建筑物重要性-建筑场地类别关系矩阵,形成了7个不同的工况;并给出了不同工况下基床系数的计算公式,便于在实际工程中,可以根据不同工况,选取对应的基床系数计算公式进行计算。
Through the analysis of different calculating methods of foundation modulus, the calculated foundation moduli respectively from Biot ( 1937 ) and Vesic ( 1963 ) and the trend of foundation modulus with foundation width, foundation height and Poisson Ratio are great different. The matrix of structure significance with site classification is established based on using functions and site classifications, and seven working conditions are obtained. The formulations for foundation modulus under different conditions are given through the analysis to these working conditions.
