Study on Rock Mass Engineering for High Dam Foundation

In the light of Ertan and Lijiaxia projects the special topic studies the stability assessment on foundation rock mass of high dam and the quality standard of available rock mass, which include investigation of engineering conditions of rock mass, quantification study of rock mass structure ,founding of original stress field and permeable medium field in dam foundation rock mass as well as influence on and assessment of rock mass engineering conditions, founding and application of grading system for rock mass engineering quality, mechanical characteristics and failure mechanism of rock mass,prediction and selection of mechanical parameters for rock mass, foundation stabilization grouting test and application, comprehensive analysis and assessment of engineering rock mass stability for high dam foundation, available rock mass study for dam foundation and optimum seeking procedure, methods and criteria for contact face of dam and foundation, monitoring design of foundation rock mass and so on.
