1 简介桩基自平衡测试技术是近年来国内外迅速发展并推广应用的一种基桩承载力检测新方法,它有效地弥补和解决了传统试桩法中难以解决的问题,诸如大直径深长灌注桩承载力检测、水上试桩、狭窄场地试桩、嵌岩桩基底承载力检测等诸多工程技术难题。本文通过对京珠国道主干线高速公路2根大直径钻孔灌注桩的单桩竖向抗压静载试验,简要阐述了桩基自平衡测试技术的基本原理、测试方法以及由自平衡试验结果向传统静载试验结果进行转化的理论依据,分析并讨论了自平衡测试技术作为一种新型的基桩承载力检测手段的先进性、合理性及
1 Introduction Pile self-balancing testing technology is a new method of testing the bearing capacity of piles, which is rapidly developed and popularized at home and abroad in recent years. It effectively remedies and resolves the problems that are difficult to solve in traditional test-pile methods, such as large diameter, long and long Pile bearing capacity testing, water test pile, narrow site test pile, socketed pile foundation bearing capacity test and many other engineering problems. In this paper, the Beijing-Zhuhai Expressway main trunk highway two large diameter bored pile vertical compression static load test, the basic principle of pile self-balancing test technology, test methods and self-balance test results This paper analyzes and discusses the advancedness and rationality of self-balance testing technology as a new measure method of bearing capacity of pile,
