Abstract:Coefficient of subgrade reaction is an important parameter in geotechnical engineering, Accurately obtai- ning the coefficient of subgrade reaction is significance to the actual project. The paper introduces the basic concepts of the coefficient of subgrade and the existing main test and calculation methods. According to the Changchun City Yitong River in - situ tests, using mathematical statistical methods to calculate the coefficient of subgrade is a simple and accurate calculation of the empirical formula.
Keywords:Coefficient of subgrade  In - situ tests  Mathematical Statistics  Empirical formula
