摘要
本文以岩石单轴蠕变试验为例,介绍了用多项式回归间接求解岩石流变力学模型中各元件的力学参数的方法,并求出了蠕变方程。该方法是通过建立试验数据多项式回归方程与理论公式多项式展开式之间的间接联系,联立方程组求解未知的物理参数。此方法简单易懂、实用,所求参数的精度符合工程要求。文中给出了计算机求解程序框图。
This paper, on the basis of rock creep test,descrihes a method to find indirectly the solution of rock rheology’s parameters with polynomial regres- sion and gives rock creep equation. By means of establishing,indirectly re-lationship between the test data polynomial regression equation and the ex- panding expression of test theoretical formula and solving simultaneous equations, the unknown physical parameters can be found.
