The research work done is presented as follows:Compound dewatering technique of vacuum tube well is an effective technology for solving the dewatering problems of aquitard and interface relict water according to physical simulation test and field test. The variation laws, such as degree of vacuum, pore water pressure in different strata, have been studied. The results show that there is a certain scope of influence of vacuum in strata, and the vacuum degree in the horizontal direction decreases gradually with the increase of the distance from the main well; the change law of degree of vacuum in the vertical direction increases firstly and then decreases with the depth of soil strata, and changes with different soil nature and depth; changes of pore water pressure in soil strata has also shown a similar law of degree of vacuum.

Consolidation test is a important link of obtaining mechanical properties index of soil and coefficient of compressibility gained through the test is a key data to evaluating the compressibility of soil. Consisting of solid phase and liquid phase of the salty soil is different from the non-salty one. Eutectic salt in soil may exist as liquid phase, solid phase or both of them and these phases can interconvert because it is affected by temperature, Na_2SO_4 content, water content. Especially when temperature drops, Na_2SO_4 will crystallize and expand, namely salt expansion of soil. These particularities make soil sample put in environmental cabinet when consolidation test is going on. So soil sample can be compressed by temperature controlling system under a set temperature.From experiment, the formulae counting coefficient of compressibility of salty soil have been given.

土的固结试验，是取得土的力学性质指标的一个重要环节，因为土的固结试验所取得的压缩系数，对评价土的压缩性是一个关键数据，但由于盐渍土的固相、液相组成和非盐渍土不同，土中易溶盐受温度、含盐量、含水量的影响可以以液相、固相、液相和固相混合形式存在，且它们之间的存在形式可以相互转换，尤其是当温度下降时，硫酸钠便结晶产生体积膨胀，即盐胀，这些特殊性就使得在进行硫酸盐渍土的固结实验时，须将土样放置在环境箱中，通过温度控制系统使土样在设定的温度下受压产生变形。
