钻孔灌注桩自平衡测试试验研究

Study of Self-Balanced Load Tests for Bored Piles

结合武汉天兴洲长江大桥的工程实践,介绍了钻孔灌注桩自平衡试桩的原理、测试设备、测试方法、分析方法等,为优化设计,保证工程质量和安全提供了准确的数据资料。

Based on the construction practice of Tianxingzhou Changjiang River Bridge in Wuhan, this paper presents the principles, test equipment, test methods and analysis procedures of self-balanced load tests conducted for the trial bored piles of the Bridge. The tests for the trial piles provide accurate data for optimal design and for securing construction quality and safety of the Bridge project.
