HAN Bing1,WANG Zhi-yin1,DING Xiu-li2,XU Ping2(1.Beijing Key Laboratory of Urban Oil and Gas Distribution Technology,China University of Petroleum,Beijing 102249,China;2.Yangtze River Scientific Research Institute,Wuhan 430010,China)  
The effects of stress level and loading path on rheologic behaviors of alternating distribution of soft and hard rock layers are investigated with triaxial and uniaxial experiments.By using the simulated software FLAC3D,the established model is analyzed with the method of 3-D visco-elasto-plastic numerical simulation.The results show that,under the same exerting loading level,the deformation and volume of plastic zone of rock mass will be increased with the increase of the number of layers,embedded depths and declination of soft rock.
