自平衡法是一种新型的桩承载力的测试方法,与传统静载荷试验方法相比,具有许多优点。东南大学土木工程学院对昆明市昆洛路改扩建工程中几座立交桥的6根试桩进行了承载力自平衡法测试。本文概述了自平衡法的基本原理,介绍了昆明地区这次测试的应用情况,并对测得的数据进行了整理和分析研究。分析研究结果表明,这次测试取得了较好的试验效果,为设计提供了可靠的依据。 Self-balance method is a new test method of pile bearing capacity, which has many advantages compared with the traditional static load test method. Southeastern University School of Civil Engineering Kunlun Road, Kunming, a number of overpasses in the six test pile bearing capacity self-balance test. This paper summarizes the basic principle of self-balance method, introduces the application of this test in Kunming area, and organizes and analyzes the measured data. Analysis results show that this test has achieved good results, providing a reliable basis for the design.
