PDA-CASE动力试桩研究

Study on PDA-CASE Dynamic Test of Pile

摘要: 本文系统地探讨CASE法在阻力分析中的波前效应。对应力波在第一个传播周期中的可能性状作了全面的描述,并结合工程实例对CASE动力试桩中的有关技术问题进行讨论,最后对试桩中可能出现的误差进行分析。

Abstract: In this paper, the effect of stress wave front on the analysis of soil resistanceis studied. The behaviour of stress wave signal In the first cycle is described. Thetechnique in relation to CASE dynamic test of pile is discussed. Finally, the error in CASE dynamic test of pile 13 estimated.
