SAFETY DEGREE EVALUATING METHOD FOR ROCK-BED SLOPE

摘要

PPROBLEM TO BE SOLVED: To provide a safety degree evaluating method for a rock-bed slope for coping with the cracked rock-bed slope having, in particular, a complicated shape. PSOLUTION: This method comprises processes of: obtaining three-dimensional coordinate data about the rock-bed to be handled; preparing a primary model of the rock-bed based on the three-dimensional coordinate data; preparing a mold for a secondary model from the primary model; preparing the secondary model by providing a heterogeneous material imitating an existing crack in a predetermined section in the mold for the secondary model and placing solidifying agent produced by blending materials aiming at strength of the rock-bed as target strength into the mold for the secondary model; obtaining centrifugal force when breaking the secondary model by conducting a centrifugal force model experiment with respect to the secondary model; and calculating a rate of safety of the rock-bed based on a rate of safety at breaking time.
