| 摘 要： | 根据土的变形特征,参考弹性半空间理论用于机器基础振动计算的常集总参数法,借鉴苏联《动力机器基础设计规范》求动力机器基础天然地基弹性均压系数Cz值的算式,针对我国地基土的实际,对不同地基土的力学系数进行修正,提出了适合我国国情的计算式,作为对GB 50040—96《动力机器基础设计规范》的补充。

| Abstract: | According to the deformation characteristics of soil,compressive stiffness coefficient Czformula was proposed.The formula was obtained by using ideas from the code of the USSR. Soil mechanic parameter was modified to match the actual conditions of subsoil in China. Lumped parameter method based on the elastic half space theory was also referenced in the formula. The method was taken as a complement for Code for Dynamic Machine Foundation Design. |
