摘要: 介绍了超大吨位自平衡法和拉锚静压法静载试验在桃花峪黄河大桥桩基承载力检测中的应用,依据自平衡法试验结果和拉锚静压法荷载试验结果的对比分析,对自平衡法静载试验进行了应用分析研究。研究发现,自平衡法将桩身分为两段、利用试桩本身来施加荷载,简单、方便,试验结果和静压法相比误差很小,可以有针对性地在大吨位静载试验中进行推广应用。

Abstract: The applications of self-balanced method and the pile load test using tension-press-anchor system under large tonnage load in static loading tests are introduced. Both the methods are used in bearing capacity tests on pile foundation of Yellow Taohuayu River Bridge. The results are compared and show that the error is very small. Using the self-balanced method, pile body is divided into two segments. The load is applied by the pile body. The proposed method is more convenient and inexpensive, and it can be popularized in engineering.
