MATHEMATICAL MODEL OF COUPLED STRESS AND SEEPAGE FIELDS IN UNLOADING ROCK MASS AND ITS PRACTICAL APPLICATION
On the basis of present study situation in the field of the mechanics characteristics of unloading rock mass and its relation with rock mass seepage, mathematical model of coupled stress and seepage fields in rock mass is set up under unloading conditions. based on the analysis in two dimension about high-steep slope of plant at Geheyan hydropower station, under the condition that unloading and seepage is coupled in rock mass, horizontal displacement and stress distribution of the slope is obtained, which is compared with the results of the ordinary condition, we can find that the former deformation is 1.5-2 times of the laters. Results show that unloading has an obvious effect on the deformation in the mathematical model of coupled stress and seepage fields.
