中文摘要：
应用C＋＋语言编写的简易数值试验程序,模拟了岩石单轴拉伸的蠕变过程。试验中采用分级加载的方法,分析了不同拉应力条件下岩石的粘滞系数与应力和时间的关系,并推出了岩石非线性粘滞系数的函数关系式。随着应力的增加,粘滞系数与应力满足反正切三角函数关系,同时随着时间的延续,粘滞系数变化率与时间也满足对数函数关系。结果表明：岩石蠕变过程是典型非线性行为,建议采用非线性流变力学进行研究。
英文摘要：
The creep process of rock under uniaxial tension was simulated with a simple C ^＋＋ numerical value programming. The relation curve is obtained between viscosity coefficient and stress-time of rock with different tensile stress in test. A function formula of nonlinear viscosity coefficient is derived for the rock. The relationship between viscosity coefficient and stress can be expressed as an inverse tangent trigonometric function as stress increases. And the relationship between change rate of viscosity coefficient and time can be expressed as a logarithm function as time prolongs. Results show that rock creep is a typical nonlinear progress, it is proposed to be studied with nonlinear rheologic mechanics .
