首先对不同土样进行了一系列室内真空固结和加载固结的对比试验，通过对试验结果的比较分析，明确了抽真空引起土样固结的原因，即抽真空作用会在四个方面对试样产生影响：毛细管势的改变、封闭气泡的排出、汽化现象及大气压的作用，而其中大气压的作用是最主要的。

Second, considering the influence of well resistance, smear effect and structure breakage of thick soft clay, the equivalent calculation method is proposed. That is, the partially penetrating sand drain ground is viewed as the double-layered ground, and its consolidation is analyzed with 1-D consolidation theory, through the transformation from 3-D consolidation to 1-D consolidation in the region of sand drain. This can overcome the disadvantage that the excess pore water is discontinuous between the region of sand drain and under-lying soft layer. To the double-layered ground, based on the consolidation mechanism under surcharge, the excess pore water pressure calculation formula is deduced under the condition of multilevel equably loading or unloading, which perfects the consolidation theory.
