| Abstract: | According to simularity criteria of elastoplastic body and simularity criteria of its damage stage,the simularity constants are determined. By simulating mountain body shape, structural sarface, physico-mechanical properties of rock, ground(initial) stress, boundary conditions and embedded measured points;a 3-dimensional model of jointed rock mass of high-steep slope is established. Through simulating load-off process due to excaration; monitoring slope deformation, ground stress-release and strain of mountain body; the recognitions obtained are as follows: main factors of slope deformation, deformation delay and deformation value, relationship between deformation and stress-release,obvious change scope of stress-strain of the mountain body. |
| Keywords: | high and steep slope rock jointed rock mass model experiments |
