Taking the muddy dolomite in the base of the dam of Yujian River Reservoir in Guizhon Province as an example, the author of the paper proposes a new research method: from rock mineral identification to indoor (or outside) test of rock intensity (or formation) finally to determination of rock mass elastic modulus. Based on rock mineral identification and comparative experiments of indoor rigid servo and in-situ point loading, this paper analyzes the clay content in dolomite, saturated uniaxial compressive strength, and elastic modulus, and the regression equation is established as well. Also, with the help of Monte-Carlo simulation technique and rock mass damage fractal modulus, this paper analyzes the elastic modulus of muddy dolomite and establishes the statistic relationship between the clay content in dolomite and the elastic modulus of the rock mass. The proposed method could be adopted in large projects in other similar regions to estimate the rock compressive strength, rock elastic modulus and rock mass elastic modulus in feasibility study when it is necessary to estimate the elastic modulus of the muddy dolomite.
