摘要
为研究孔灌注桩的承载特性,采用自平衡测试法进行4根试桩静载荷试验,并采用钢筋计测试元件进行了桩身轴向应力测试。基于实测数据,对桩总承载力、桩侧摩阻力、桩端阻力以及承载力性能进行了分析。研究表明,南岸试桩桩侧摩阻力地勘报告值与实测值基本一致,南岸锚定区试桩桩侧摩阻力地勘报告值与实测值存在一定差异。试验研究成果直接用于该工程桩基设计,同时为类似桩基设计施工提供参考。
To obtain the bearing characteristics of bored piles, the Osterberg method test on four single piles in compression and the axial stress test along the shaft based on strain gauges embedded in piles were conducted. Based on the test results, bearing capacity, side friction, tip resistance and load bearing properties of the piles were analyzed. The results indicated that the friction values of investigation report were close to the piles in south coast while the friction values of investigation report had some differences with the piles in south coast anchorage area. The research results were applied in the design of piles of this project, and it can also provide reference for design and construction of similar bored pile.
