单桩上拔静载试验循环加卸载方法分析研究

Analysis of Cycling Load-unloading Method on Uplift Test of Pile

本文以科学实验方法论的观点，结合工程实例，论述了单桩竖向上拔静载试验循环加载方法的特点及其应用条件。指出：试验加载方法的仿真性、可操作性、使试验结果具备可比性，是合理制定和选择试验加载方法的三个要素，是决定试验方法是否具有生命力的主要因素。

On the principle of scientific experiment and combined with engineering example, the characteristics and using conditions of cycling load-unloading method on uplift rest of pile are discussed. In this paper,three essential factor about rationally making and choosing the test of loading method have been rised. These are emulation property,operated easily and that the test results are able to contrast each other.
