In order to explore the genetic mechanism and ecological governance model of the landslide and collapse geological disaster on the unstable slope in the Metamorphic rock area of northwest Hubei, the unstable slope in the bedding Metamorphic rock of Sanyongtang was chosen as the research object, on the basis of identifying the geological and deformation characteristics of the disaster body, the possible failure modes and main influencing factors were analyzed, and the mechanism of progressive deformation and failure of bedding metamorphic rock slopes was deeply explored. The stability calculation and evaluation of an unstable slope were conducted using methods such as limit equilibrium, and the results show that the slope was in an unstable state. Based on the concept of ecological management of geological disasters, the comprehensive prevention and control measures have been proposed, including cutting and shaping, foot protection walls, framed anchor, truncation drain, ecological greening and monitoring. Through engineering implementation and effectiveness monitoring, it has been shown that this treatment scheme not only effectively eliminates the safety problem of landslide and collapse geological hazards in the Sanyongtang, but also achieves good environmental greening and beautification effects. Its comprehensive prevention measures, especially the ecological governance mode integrating geological disaster prevention and ecological greening, can provide reference for the reinforcement and slope protection of similar bedding Metamorphic rock unstable slopes.
