岩体节理剪切变形的幂函数模型

POWER FUNCTION MODEL OF SHEAR DEFORMATION FOR ROCK JOINTS

在分析了岩体节理剪切变形常用双曲线模型和指数模型的基础上 ,提出了一种幂函数模型。用幂函数模型描述的回归曲线以及根据试验参数得到模拟曲线与试验值比较误差均较小。最后 。

On the basis of analyzing hyperbola and exponent models in common use, the power function model of shear deformation is presented for rock joints. The errors of the data obtained using the power function model are very small from the test data. In the end, the impact factors of parameters in the model are analyzed.
