在役码头桩基承载力静载试验

传统在役码头的桩基承载力检测需拆除上部结构,使得检测工作量大且工期较长。以某旧码头桩基检测工程为依托,阐述在保持上部结构完整的情况下,快速准确检测桩基承载力的方法。首先通过数值模拟分析上部结构与桩基荷载分担比例,初步确定试验堆载量。同时在码头下部的桩头安装传感器,加载过程中能较精确的测得桩顶的实际荷载。用该方法顺利地对该码头2根桩承载力进行检测,取得了较好的效果。

Static load test on bearing capacity of piles in service

The traditional static load test on the bearing capacity of piles in wharf needs to dismantle the upper structures,which costs large workload and long time.Based on the project of pile tests of an old wharf,we elaborate a fast and accurate method of pile static load test which maintains the integrity of the upper structure.The amount of loads was preliminarily determined through analyzing the load sharing ratio of pile by the finite element method.The sensors which can measure the loads on pile were installed on the pile top,and the bearing capacity of two piles were tested successfully by this method.
