超大群桩竖向承载群桩效应试验研究

Model Test Study on Effect of Vertical Bearing Capacity for Large?scale Pile Group

根据竖向荷载作用下超大规模群桩的模型试验研究结果,分析群桩的承载性状和群桩效应,试验结果表明,在本试验条件下,群桩效应系数大于1,与按规范公式计算得出值基本一致,并得出一些对该类工程设计和施工具有指导意义的结论。

Based on the model test's data of very large?scale pile group under vertical load,this paper analyzes the bearing behavior and the effect of pile groupThe test results have indicated that the effect coefficient of the pile group is greater than 1 under the test condition and it accords with the calculated value from the code formula and some conclusions are obtatied for engineering design and constructio
