摘要
针对超长大直径灌注桩,通过苏通长江公路大桥现场静载测试和模型试验,对桩侧摩阻力和桩端阻力的荷载传递机理、承担荷载的比例及其影响因素、荷载-沉降关系等进行了研究,得出超长大直径灌注单桩的荷载传递特性。
To counter super-long and large diameter pouring single pile, the load transferring mechanism of pile side friction and pile end friction, the bearing load ratio and its effective factors, the relationship between load and settlement are researched through the static load tests in site and the centrifugal model tests of Sutong Yangtse River Highway Bridge, some load transferring characteristics of extra-long and large diameter pouring single pile are gained.
