The author used the pressure experiment of the saturated clay with different hydrophilic property, to determine the relationship between film water discharges in saturated clay and pressure. On the basis of this relationship, mechanism and rule of saturated clay with film water releasing. According to the relationship between pressure and void ratio, establish the relevant function relation between hydrophilic property, void ration and film water in the saturated clay. The research show that the film water is discharged only by hydrophilic and void ratio effect, not affected by other factors. External pressure can affect the film water discharged into clay indirectly, resulting that the pore discharge volume is greater than the soil compression volume. And the difference value nonlinealy increases with external stress increases, the difference value and void ratio is the natural logarithm relationship.%利用亲水性各异的饱和黏性土,开展不同压力条件下的压密试验,确定试验条件下黏性土中弱结水释水过程对外界应力的响应关系；依据响应关系,研究饱和黏性土中弱结合水的释水机理与规律；再根据土体孔隙比与压力之间对应关系,构建出饱和黏性土中亲水性、孔隙比与弱结合水之间的函数关系.研究表明:土体中弱结合水排出只受土体亲水性大小与孔隙比大小影响,不受其他因素制约；外界压力通过改变土体中的孔隙比大小,从而间接影响到土体中弱结合水排出,导致排水总体积大于土体压缩总体积,两者的差值随外界压力增加而呈非线性关系增大,与孔隙比呈自然对数关系.
