Gm (1,1) Model Analysis of Swelling Rock Mechanical Properties in Hydraulic Electric Power Project

Abstract:

In the construction of hydraulic electric power, softening and slaking of swelling rock is a natural phenomenon, which is a complex process and affects the stability of rock engineering. It is difficult to describe and predict quantitatively the dynamical properties of the soft rock making use of a common method. Grey theory has proven successful in research such a complex system. This paper proposed GM(1,1) model based on remanent error analysis to the experimental fitting value of gargillite mechanical parameters, which is regarded as a new way of describing the nonlinear mechanical properties of soft rock and applied to predict the instability of engineering rockmass.
