为了探索水和石膏耦合对黄土湿陷性的作用规律，以黄土的含水量和石膏含量为因素，设计混合均匀试验方案，进行了黄土湿陷性的水石膏耦合效应研究，应用最小二乘拟合，建立了湿陷系数与石膏含量、含水量的非线性回归数学模型。结果表明，石膏含量对黄土的湿陷性有显著影响，黄土湿陷系数与石膏含量、含水量均呈递减的指数关系，水和石膏耦合有利于降低黄土的湿陷性。

In order to explore the coupling effect of water and gypsum on loess collapsibility a uniformly mixing test scheme was carried out to study the coupling effect based on the factors of moisture content and gypsum content of loess.The nonlinear re-gression mathematical model between the collapsibility coefficient and gypsum content and moisture content was developed by the least squares fitting method.The results showed that gypsum content has significant effects on loess collapsibility,the loess collapsibility coefficient has a decreasing exponential relationship with gypsum content and moisture content,and the coupling of water and gypsum can decrease the collapsibility of loess.
