【摘要】 对含氯盐和硫酸盐类盐渍土的盐胀规律及影响因素进行了较为系统的试验研究，得出了盐胀随温度变化的若干规律，即盐胀随温度变化的关系式，起胀温度与各影响因素之间的关系式，盐胀与降温速率的关系式，成型温度对盐胀规律的影响等。分析了Ｎａ２ＳＯ４含量、ＮａＣｌ含量、Ｃｌ－／ＳＯ２－４、含水量对盐胀的影响，给出了盐胀与各影响因素之间的关系式。更多还原

【Abstract】 In this paper, based on experiments, salt expansion and its influencing factors for soil with Na 2 SO 4 and NaCl are systematically studied Some salt expansion relations are obtained, such as relation of salt expansion to temperature changing, relation of expansion starting temperature to influencing factors, relations of the range of salt expansion rapidly changing to concentration of Na 2 SO 4 , relation of salt expansion to cooling rate, relation of salt expansion to shaping temperature etc The effects of Na 2 SO 4 solution, NaCl solution, Cl - /SO 2- 4 and water content on salt expansion are analysed and Corresponding formulas are put foward更多还原
