【摘要】 通过采用自平衡测试法对杭州湾跨海大桥南岸滩涂区基础试桩进行测试,转换以后得到了荷载~位移曲线、桩周土的侧摩阻力和端阻力的分布。转换以后的数据表明,实测桩周土摩阻力要远大于地质报告给定的摩阻力,说明了由地质报告确定桩长较保守,最后给出了优化以后桩的持力层。更多还原

【Abstract】 The self-balanced testing method is applied to measure the bearing behavior of foundation testing piles of Hangzhou Bay Sea-Crossing Bridge in tidal-flat area on south bank.The pile load～displacement curve and distribution of lateral frictional resistance of soil around piles and pile base soil resistance are obtained through conversion of results of the tests thereof.Testing results indicate the real frictional resistance of soil around piles is more than the frictional resistance made by geological survey report,it is conservative that the pile length is determined by geological survey report.Last,bearing stratum of pile foundation in the zone after optimization is recommend.更多还原
