某码头工程大直径嵌岩桩的承载力试验

Bearing Capacity Test for Large-diameter Rock Embedding Pile in Terminal Project

以重庆港寸滩作业区某码头工程的大直径嵌岩桩承载力试验为例,试验中采用自平衡测桩法确定大直径嵌岩桩的竖向承载力,根据桩身变形和内力测试数据估算嵌岩桩的水平承载力,通过分析嵌岩桩的荷载传递机理,探讨更好地发挥嵌岩桩桩侧摩阻力的途径和方法,可为嵌岩桩的优化设计提供参考。

Self-balancing method for pile testing is applied for determining the vertical bearing capacity of large-diameter rock embedding pile by referring to the relevant bearing capacity test made in Cuntan Operating Zone Terminal Project of Chongqing Port. Horizontal bearing capacity of the rock embedding pile is estimated according to the pile deformation and the testing data of internal force. The load transfer mechanism of the rock embedding pile is analyzed to discuss the way to make good use of pile lateral friction of the rock embedding pile, which will provide references for the design optimization of the rock embedding pile.
