基于真空测试原理论述了已有关于真空度传递研究结论存在很大差异的主要原因,并给出了从理论上研究真空传递规律的途径,从理论上说明了真空预压加固深度不仅和真空度传递衰减有关还和软土地基的地下水位高度有关。%Based on the vacuum testing theory, the reason leading to the difference among the vacuum transmitting theory in exiting research were illustrated in this paper, and the method for studying the vacuum transmitting law was conduct. Finally, it was found that the vacuum preloading consolidation depth was not only relied on the vacuum transmitting attenuation, but also related to the ground water level of soft clay ground.
