Abstract: A method for establishing a geostress field distribution of slopes in canyon areas includes: obtaining a persistence ratio of a fracture surface based on a structural plane trace length and a rock bridge length of the fracture surface, and then obtaining a fracture stage of a crack according to progressive failure characteristics of rock mass, combining a character of the fracture surface to obtain magnitude and direction of a maximum principal stress, and establishing the geostress field distribution. The method is simple to operate, does not need to carry out geostress testing, does not need a large amount of manpower and material resources, does not need redundant fund investment, and can simply and effectively obtain geostress field data. Moreover, combining with the geostress field inversion technology, a large-scale geostress field distribution condition can be obtained, which can provide a basis for engineering site selection and engineering rock mass stability determination.
