Rock mass stability analysis method and device, terminal and storage medium

The invention provides a 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 rock mass; calculating the contact force of each structural surface of the target movable block; according to the gravity of the target movable block body and the contact force of each structural surface of the target movable block body, calculating the resultant force of the active force borne by the target movable block body; according to the main power resultant force and a preset safety coefficient calculation formula corresponding to the multiple motion modes, the safety coefficient of the target movable block is calculated; and generating a stability analysis result of the target rock mass according to the safety coefficient of the target movable block body. According to the method, the influence of the acting force between the blocks on the translation and rotation stability of the key blocks is considered, and the s
