Abstract

The invention provides a fractured rock mass stability analysis method and device, a terminal and a storage medium. The method comprises the following steps: searching all movable blocks in a target fractured rock mass; calculating the seepage force of each fracture surface of the target movable block; according to the gravity of the target movable block body and the seepage force of each fissure surface, calculating the resultant force of the active force borne by the target movable block body; according to the seepage force of each fissure surface and the preset water weakening rate corresponding to the corresponding seepage force, the water weakening cohesive force of each fissure surface is calculated; according to the main power resultant force, the water weakening cohesive force of each fracture surface and a preset safety coefficient calculation formula corresponding to the target movable block, the safety coefficient of the target movable block is calculated; and generating a stability analysis result of the target fractured rock mass according to the safety coefficient of the target movable block. According to the method, the seepage force of the fluid in the fractured rock mass and the weakening influence of the fluid on the structural surface can be finely considered, and a comprehensive and accurate stability analysis result of the fractured rock mass can be obtained.

Description

technical field [0001] The invention relates to the technical field of rock mass engineering, in particular to a stability analysis method, device, terminal and storage medium of a fractured rock mass. Background technique [0002] Rock mass is a geological body composed of structural planes and structural bodies with discontinuity, heterogeneity and anisotropy, and occurs in a certain geological environment. Due to geological tectonic action, there are various types of discontinuous structural planes such as material interfaces, faults, weak interlayers, and joints in the rock mass. In rock hydraulics, these discontinuous structural planes are collectively called fissures. [0003] At present, there are two main types of theoretical analysis methods for rock mass stability: one is continuous medium analysis methods, such as finite element method, finite difference method, and boundary element method; the other is discontinuous medium analysis methods, such as discrete eleme...
