He has been engaged in theoretical and applied research on rock mechanics and geotechnical engineering for a long time. His research fields include experimental research, physical simulation and numerical analysis of underground engineering, slope, dam stress, stability and optimization, as well as rock rheological mechanics, concrete creep mechanics and intelligent rock mechanics. As the main finisher, he won the second prize of National Science and Technology Progress Award in 2004, the first prize of Hubei Science and Technology Progress Award in 2003, each 1, and the Excellence Award of President of China Academy of Sciences in 2003. In recent five years, he has published more than 30 papers in international and domestic journals, 4 papers in international journals in this field, 4 papers in international academic conferences and 7 papers in Chinese core journals, including 4 papers included in SCI, 2 papers included in EI 10 and 2 papers retrieved by ISTP. He has co-published 2 books and participated in the compilation of the specification1; Obtained 1 utility model patents and software registration rights through cooperation. At present, as the person in charge, he has undertaken the national natural science foundation project "Experimental and theoretical research on rheological properties of rock mass under the coupling effect of stress and water physics and chemistry", Qinghai province's major scientific and technological key project "Study on surrounding rock stability and reasonable supporting measures of large underground cavern under high stress", and Chinese Academy of Sciences' innovative major directional project "Key technical problems in deep underground engineering development" and other 1 projects. He is the main participant and academic backbone of the national key basic research and development plan 973 project "Basic research on safety of major projects in disaster environment" and the national outstanding youth science fund project "Stability analysis and optimization of underground projects under high stress". As the main researcher, he has completed two key projects of 1 and general projects of the National Natural Science Foundation. Participated in the completion of Sino-Italian international scientific and technological cooperation and exchange projects, and presided over the completion of each 1 project of Wang Kuancheng Fund with Lille University in France. He has presided over or participated in more than 30 large and medium-sized hydropower engineering scientific research projects, such as Three Gorges of the Yangtze River, Ya Bu of Qingjiang River, Laxiwa of the Yellow River, Danjiangkou Heightening of South-to-North Water Diversion Project, Pengshui of Sichuan, Goupitan of Guizhou, Baise of Guangxi, Puding of Guizhou, Guanyinge of Liaoning, Mianhua Beach of Fujian, Daguangba of Hainan, Tianshengqiao of Yunnan and prevention and control of geological disasters in the Three Gorges reservoir area.
