自平衡试验在武汉光谷中心项目工程中的应用分析

Applied Analysis of Self-balancing Test in the Project of Wuhan Optical Valley

本文结合武汉光谷中心项目工程的实例,详细介绍了在该工程中自平衡试验的原理和具体操作过程,并根据自平衡试验所得的数据,分别采用技术规程公式和等效转换曲线两种方法对桩基的承载力进行了分析研究,结果表明通过自平衡试验能够有效且精确地得到建筑物试桩承载力数值,可为建筑物的设计和施工提供依据;另外,对现阶段利用自平衡试验检测桩基承载力的方法提出了建议,对现阶段桩基检测以及自平衡测试技术的理解和研究具有一定的意义。

In combination with the project in Wuhan Optical Valley, this paper describes in detail the application of the principle and operation of self-balancing test. With the data from the test, the paper analyzes and studies the capacity of file by two methods：technique prescription formula and equivalent conversion curve. The results show that the capacity of pile can be obtained effectively and accurately with self balancing test and thus facilitates the design and construction of the building , In addition, the paper gives some reasonable advices to the method which have certain significance for the current test of pile and for the understanding and research of self-balancing test.
