摘要
本文在调查研究和模型试验的基础上，对群桩的工作性状与破坏机理、单桩与群桩的应力应变关系进行分析研究。提出了群桩承载力分配不均匀的效率系数公式和把排桩中“后桩”修正为单桩计算的土反力折减系数公式。
Based on investigations and model tests,a series of studies has been performed on the behavior and failure mechanism of laterally loaded pile groups, the stress strain relationship for single pile and pile groups, and so on. An efficiency formula for non uniformity of load distribution in the longitudinal direction of pile groups and a revised formula for P Y curves of individual pile in pile groups are put forward. All these results are verified by some practical case records.
