摘要
本文运用有效应力路径的分析方法,着重分析了砂井堆载预压法(简称SDP法)和砂井真空排水预压法(简称SDVP法)的加固机理和不同的加固特征,从而以土力学的观点,指出SDVP法比SDP法更适合于加固软土。
In this paper, the mechanism to improve the ground soil by the Sand Drain Preloading method (abbreviated; SDP method) and the Sand Drain Vacuum Preloading method (abbreviated SDVP method) and the different stabilization features ereanalysed by the effect stress path method. From the point of view of soll mechanics and foundation engineering, SDVP method is more suitable for improving soft clay than SDP method. Finally, two engineering examples are presented.
