Application of E.Hoek method to evaluating mechanical parameters of closely jointed rock mass--A case study of Baiyian Landslide in Three Gorges area

The determination of mechanical parameters of jointed rock mass is a difficult and key problem in evaluating stability of rock engineering. In 1980, E.Hoek brought forward and advanced a method to solve this problem, which includes the characteristic of the jointed rock mass especially. The principle of E.Hoek method is introduced systematically; and the key issues in operating by this method are discussed. Then a case study of jointed rock mass of Baiyian landslide in the Three Gorges area is expounded. It is shown that the E.Hoek method, which is effective and feasible, may precisely reflect the mechanical behavior of the jointed rock mass. As a result, the E.Hoek method is suggested to apply to similar rock engineering.
