| Abstract: | This paper firstly summarized the existed methods for estimating the deformation modulus,and discussed its working conditions and prediction results.Based on previous research results and 55 group data from two hydropower stations in Yellow River,secondly,the paper has developed several predictor formulas using to estimate deformation modulus of rock mass,and explained the difference of estimated values by various methods.In the last,a suitable pre-estimating formula was suggested. |
