本文以Ｔｅｒｚａｇｈｉ一维固结理论解为基础，进一步研究Ｓｃｏｔｔ法求团结系数方法，推导出ｎ＝２，３，４的三种Ｃｖ计算式，根据试验资料可直接计算出Ｃｖ；本文还改进三点法的表达式，全部用试验数据表示；又提出了理论零点ｄ０的统计计算法，该法的结果与原标准法是一致的；但方法简捷方便，便于计算器计算。 Based on Terzaghi’s one-dimensional consolidation theory, this paper further studies Scott’s method of calculating unity coefficient, and derives three Cv formulas for n=2,3,4. According to experimental data, Cv can be calculated directly; The expression of the point method is all represented by experimental data; the statistical calculation method of the theoretical zero point d0 is also proposed. The result of this method is consistent with the original standard method; however, the method is simple and convenient, and it is easy for the calculator to calculate.
