本文提出了徐变系数与收缩率的解析表达式,其计算结果与CEB-FIP(1970～1972)建议的图解法相近. 首先用最小二乘法建立一组非线性方程;然后用K.M.Brown制定的数解法求解 编制电算程序后,可把这些解析表达式作为改善按所谓Dischinger假设或修正的Dischinger假设那样简化的徐变定律求近似解的一种方法。
In this paper, the analytical expression of creep coefficient and shrinkage rate is proposed, and its calculation results are similar to those proposed by CEB-FIP (1970 ~ 1972) .Firstly, a set of nonlinear equations are established by least square method; After solving the programming algorithm by the numerical solution, these analytical expressions can be used as a method to find the approximate solution to the simplification of the creep law, which is based on the so-called Dischinger assumption or the modified Dischinger assumption.
