自平衡法在砂泥岩地层基桩承载力检测中的应用

Application of Self-balancing Method in Bearing Capacity Test of Foundation Pile in Sand-Mudstone Formation

自平衡法作为一种新型的单桩承载力测试技术,能有效地检测大吨位基桩的承载力。结合工程实例,从基桩抗拔承载力检测的自平衡试验原理、试验方法及检测结果阐述了自平衡试验在基桩抗拔承载力检测中应用。试验结果表明:在桩基承载力检测试验中,自平衡测试法是一种有效、快捷的测试方法,测试结果可靠,可以在类似工程中推广使用。

As a new type of single pile bearing capacity testing technology,the self-balance method can effectively detect the bearing capacity of large tonnage piles.Based on an engineering example,this paper expounds the application of self balance test in the detection of uplift bearing capacity of foundation piles from the principle,method and result of self balance test.The test results show that the self balance test method is an effective and fast test method in the test of bearing capacity of pile foundation.The test results are reliable and can be widely used in similar projects.
