| 摘 要： | 通过采用自平衡测试法对杭州湾跨海大桥南航道桥基础试桩进行测试,转换以后得到荷载~位移曲线、桩周土的侧摩阻力和端阻力的分布。测试结果表明:钻孔灌注桩的施工工艺能够达到设计要求;桩端注浆对提高桩基承载力和控制桩顶沉降效果显著。

| Abstract: | The pile load-displacement curve and distribution of frictional resistance of soil(around) piles and pile base soil resistance were obtained through tests of the trial piles for pylon foundations of the south channel bridge of Hangzhou Bay Sea-Crossing Bridge with pile self-balanced load test method and through conversion of results of the tests thereof.The results of the tests indicate that the construction technology to be adopted for the bored piles of the pylon foundations of the bridge can meet the design requirements,and the effect of grouting at the pile bases is obvious in improving bearing capacity of the piles and controlling pile settlement. |
