通过室内模拟试验，研究了硫酸盐渍土在历经多次冻融循环时的盐胀累加规律，得出了盐胀累加的不同类型，给出了累加盐胀率与循环次数之间的关系式，进一步揭示了盐胀累加的机理和影响因素，为工程设计考虑多年冻融循环作用下，盐胀的累加提供了科学的依据．
Through indoor simulation experiments, the law of salt accumulation in sulphate soils after repeated freeze-thaw cycles was studied and the different types of salt accumulation were obtained. The relation between accumulated salt expansion rate and the number of cycles was given , Which further reveals the mechanism and influencing factors of salt accumulation and provides a scientific basis for the engineering design to consider the accumulation of salt expansion under the effects of many years of freeze-thaw cycles.
