摘要
以云南澜沧江特大桥桩基为背景,利用桩承载力自平衡测试技术检测桩基竖向承载力,并对测试结果进行分析,深入研究了当桩全长嵌入岩层时的竖向承载机理,分析了桩侧摩阻力、端阻力的发挥程度以及其影响因素,得出了此类桩受荷机理与普通桩的不同点。
Based on the site testing of full-length rock-socked piles from Lan Cang Jiang Bridge and by use of self-balanced testing technique,the results of the test are analyzed and the vertical bearing mechanism of the full-length rock-socked piles are deeply discussed in this paper. Moreover,the way of exertion of shaft resistance and end bearing capacity, as well as the influential factors of them are analyzed, the difference between the piles of this kind and the ordinary piles is also educed in this paper.
