| 摘 要： | 从减少承台基础的差异沉降观点出发，完成群桩系统计算模型的基础上，建立群桩-承台体系共同作用的线性和非线性数值分析方法，将中厚度板理论应用于承台基础的分析中，找出承台厚度的变化对减少基础差异沉降的影响，得到了最佳承台厚度的估算公式。对传统的桩-土体系分析中的有关参数在基础差异沉降中所起的作用做了进一步的分析，得到一些有意义的结果。

| Abstract: | This paper presents the linear and non-linear numerical analysis method in terms of reducing the differential settlement of load-bearing abutment foundation and on the basis of completion of calculation model of cluster pile system. It applies the medium-thick plate theory in the analysis of load-bearing abutment foundation and finds out the influence of the change of load-bearing abutment thickness on the reduction of foundation differential settlement and obtains the estimate equation for optimal thickness of load-bearing abutment. The effect of relevant parameters, generated from the analysis of traditional pile-soil system, occurred in foundation differential settlement is further analyzed and some significant results are obtained. |
