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。 The self-balance test was used to test the basic test pile in the South Bank of Hangzhou Bay Bridge. After the conversion, the load-displacement curve and the lateral friction and tip resistance of the soil around the pile were obtained. The data after the conversion shows that the friction resistance of the measured soil around the pile is much larger than the frictional resistance given by the geological report, which shows that the pile length is more conservative determined by the geological report, and finally the pile holding layer after the optimization is given.
