“…Chen Zuyu [2] improved the Goodman-Bray method considering the connectivity of bottom slip surface and the tensile strength of rock bridge. A large number of scholars at home and abroad have carried out in-depth research [3][4][5][6][7]. There are many toppled and deformed rock masses on the bank slope of Miaowei Reservoir on Lancang River, and after reservoir impoundment, the toppling deformation intensifies, resulting in the collapse of the slope surface.…”

By analyzing the instability characteristics of deformed body after impoundment and using limit equilibrium algorithm and UDEC discrete element simulation, the failure mechanism and stability of deformed body are studied in the paper. According to the deformation degree and instability characteristics of the deformed body in different storage periods, the mechanism of instability is analyzed. Based on the regional topographic map, a two-dimensional limit equilibrium model is established to calculate the potential failure surface range and slope stability factor of QD18 deformed body under the conditions of 1314m, 1364m and 1401m water level storage. And the displacement nephogram, velocity nephogram and rock block deformation map of the deformed body under the condition of 1401 m water level are simulated by using the discrete element software, and the stress changes of each part of the deformed body after water storage are analyzed, and the failure mechanism is summarized.

“…The research on the stability of deformed slope is one of the key topics of Engineering geology, so many scholars at home and abroad have carried out in-depth studies [1][2][3][4][5][6]. The engineering geological conditions of the deformed body are complex, such as fissures, weak interbeds, faults and intersections of various structural planes distributed in the deformed body.…”

The stability of granite deformation body in a pumped storage power station is studied in the paper, and the research includes field geological survey data collection, analysis of distribution law of structural plane, study on failure model of deformed body and prediction of deformation body stability. Based on that, the failure modes and stability of deformed bodies are studied in detail. According to the regional topographic map of deformed body, a two-dimensional limit equilibrium model is established. The three-dimensional model is established by using 3DEC discrete element software. The stress, strain and displacement under natural and rainstorm conditions are calculated and analyzed respectively, and the accuracy of the calculated results is determined by comparing with the monitoring data, so as to predict the deformation direction and rate of the deformed body. The longest movement distance of the deformed body along the shear outlet of different elevations is simulated separately to determine the affected area, which provides a reliable basis for making preventive measures for the construction site.
