| 摘 要： | 运用改进的Geddes应力解计算软土地基基桩荷载产生的附加应力及Boussinesq解计算承台下土分担的荷载产生的附加应力,将两部分附加应力线性叠加，按分层总和法计算疏桩基础的沉降。通过工程实例的计算，并与规范法的计算相比较，结果表明，改进的联合解法经济、安全，且具符合实际的荷载传递机理。

| Abstract: | Additional stress produced by soft foundation pile load is calculated with improved Geddes stress solution and that produced by soil sharing load is calculated with Boussinesq solution Then sparse pile foundation settlement is calculated through linear superposition of these two additional stress with layerwise summation method.Calculation is carried out according to engineering practice,and compared to the result with standard method,it is shown that improved combination solution is economical,safe and in conformity with practical load transfer mechanism. |

| Keywords: | soft soil composite sparse pile foundation with settlement reduction settlement calculation improved combination method |
