摘要
绍兴滨海新城滨海大桥工程桩基础具有设计承载力高、工期紧张、桩位处于江水中等特点,对该项目中1个主桥桥墩和1个引桥桥墩各选取1根钻孔灌注桩采用自平衡试桩法进行基桩检测试验。通过试验确定单桩的竖向抗压极限承载力,验证地质勘探报告中桩基参数的可靠性,并测定桩身截面位移量。试验结果表明,单桩试验实测极限承载力满足设计要求。
The pile foundation of the Binhai Bridge project in the Shaoxing Binhai New City faces the challenges of high design bearing capacity, tight construction schedule and the in-water pile site. One bored pile was taken from a main bridge pier and an approach bridge pier respectively to carry out pile test, using the self-balanced method. The test was done to ascertain the vertical ultimate compressive bearing capacity of a single pile, verify the reliability of the pile foundation parameters in the geological survey report and measure the displacement of the pile shaft sections. The result of the test shows that the measured ultimate bearing capacity of a single pile can meet the design requirement.
