摘要
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。
The Self-balanced method is a new method for the testing of the bearing capacity of pile. Compared with the traditional method of static loading test, the said method is of many advantages, using the method carries out the tests for the bearing capacity of six piles used in the municipal engineering of Kunming. The fundamental principle of the method and the application situation of the tests are introduced and the testing data are analyzed. The results from the analysis indicate that the tests with the said method get good effect, which could give the reliability for the design of piles.
