| 摘 要： | 根据竖向荷载作用下超长群桩的模型试验数据，分析了黏性土中桩距为6d的高承台超长群桩的承载性状和群桩效应．结果表明：按理论公式计算得到的群桩效应系数与试验值较吻合，理论值对实际工程中超长群桩承载力的计算是偏于安全的，可为今后超长群桩的设计提供参考．

| Abstract: | Based on the model test data of super-long pile group under vertical load, we analyzes the bearing behavior and the effect of super-long pile group with 6d pile spacing high cap in cohesive soil. The results showed that the effect of coefficient of the pile group from the theoretical formula accords with the test value, and the theoretical value is reliable to be used to calculate the bearing capacity in engineering projects, so it can offer a reference for the design of super-long pile group. |
