摘要
文章以宁波火车南站改建工程为背景,采用自平衡试桩法对大直径超长钻孔桩进行静载荷试验,成功而方便地检测大吨位钻孔桩的抗压抗拨承载力、极限端阻力及桩身上下段的极限侧摩阻力。结果表明,测试取得了较好的工程效果,可以在类似工程中推广使用。
Taking the reconstruction project of Ningbo South Railway Station as background, this paper develops the static load test to the large diameter bored piles with self-balanced test piles method, and successful and easily tests the compressive resistance capacity, ultimate tip resistance and the ultimate side friction on the upper and bottom section of the large tonnage bored piles.And the result shows that the test achieves better project effect, and it can be used in similar project.
