Abstract

The invention discloses an early warning method for rock landslides on joint surface sliding surfaces, belonging to the field of rock landslide prevention and control, comprising the following steps: a. determining the friction angle of sliding surfaces; Body area A, landslide upper side area A u , the slope β of the upper side of the landslide body; monitor the rainfall, and obtain the rainfall duration D and the average rainfall intensity I; c, calculate the early warning comprehensive discriminant factor P of the landslide; d, divide the early warning level of the rocky landslide on the joint surface sliding surface. The present invention studies the characteristics of the sliding surface, terrain conditions and rainfall conditions formed by the rock landslide on the sliding surface of the joint surface, makes a comprehensive judgment on the occurrence of the landslide, and establishes an accurate early warning calculation model for the rock landslide on the sliding surface of the joint surface , to accurately divide the possibility of landslides in a quantitative way, and has a good early warning effect on rock landslides on the joint surface sliding surface.

Description

technical field [0001] The invention relates to the technical field of prevention and control of rock landslides, in particular to an early warning method and application of rock landslides on joint surface sliding surfaces. Background technique [0002] According to the material composition, origin, nature and failure mode of the sliding surface of rock landslide, the sliding surface of rock landslide can be divided into weak interlayer sliding surface, rock layer sliding surface and joint surface sliding surface. The sliding surface of the joint surface has a good opening degree, and the surface is generally rough, which may be filled by various muddy and calcareous cements. The reason for the formation of the sliding surface is analyzed, and the sliding surface of the joint surface is formed under the action of structure and supergeneity. [0003] Rock landslides on sliding surfaces of joint surfaces are generally not easy to occur, but once they occur, they often cause ...
