Abstract: The first part of this paper considers the soft structural surface of rock masses to be a determinative factor which infuences the stability of slopes, and proposes the evalution method for the stability of rockslopes under blasting conditions.
The second influence factors of blasting crack, and considers that the orientation of blasting crack is in relation to the direction of blasting operation, finally proposes the procedure to avoid the blasting crack influencing the stability of rock slopes.
