Method and device for evaluating long-term stability of rock mass engineering

The embodiment of the invention provides a rock mass engineering long-term stability evaluation method and related equipment, which can improve the prediction precision of rock mass engineering long-term safety and failure probability. The method comprises the following steps: carrying out elastic-plastic analysis of mechanical parameter randomness and variability on a target rock mass project corresponding to a target rock mass to obtain a predicted deformation field, a predicted stress field and a predicted damage area of the target rock mass; determining the deformation failure tendency of the target rock mass project according to the predicted deformation field; determining the stress failure tendency of the target rock mass project according to the predicted stress field; determining the cracking damage tendency of the target rock mass project according to the predicted damage area; determining a multi-factor comprehensive early warning evaluation model of the target rock mass project according to the de
