The calculated results are highly consistent with the actual deformation state.įLAC3D can very accurately simulate the flow and plastic failure of materials and can be used for foundation design and slope stability. proposed that three-dimensional numerical simulation is more targeted for the deformation analysis of irregular section slope, and the influence of section morphology change on slope deformation can be considered.
used FLAC3D to establish a numerical model of a large-scale open-air slope, and through three-dimensional numerical simulation revealed the mechanical environment of a large-scale open-air slope, and discussed the movement and deformation, stress distribution, and failure mechanism of surrounding rock.

used discrete element UDEC software to simulate the antidipping soft and hard rock mass interbedded slope and systematically studied the deformation and failure mechanism of its seismic response. used numerical simulation to determine the critical length of instability failure during excavation of a multilayer soft interbedded rock slope. used the discrete element method to carry out the full-time dynamic analysis of the slope rock mass and discussed the dynamic response law and stability of the slope rock mass under the action of earthquake. proposed that the most effective methods for studying the influence of rainfall factors on slope stability are indoor and outdoor experiments and numerical simulation methods. used the discrete element method to study the deformation and failure characteristics of a total of 270 slope models under different working conditions. put forward a constitutive model that can reflect the working principle of yielding anchor cable and successfully realized the numerical simulation method of yielding anchor cable slope reinforcement by combining FLAC3D software and FORTRAN programming language.
Among them, FLAC3D numerical simulation software is good at analyzing large deformation problems in geotechnical engineering, and it adopts display calculation method, which can ensure that better calculation results can be obtained even without convergence of calculation. In terms of model establishment and control theory, such as discrete element (DEM), discontinuous deformation (DDA), Dan, smoothed particle flow (SPH), particle flow program (PFC), and tsunami ball, some numerical simulation software came into being, such as FLAC, UDEC, PFC, 3DEC, and geo slope.

At present, a series of numerical methods have been developed for different types of sliding bodies, such as finite difference method (FDM) and finite volume method (FVM). It can present the realistic slope and its geological environment, strata, and lithology and whether there is joint surface in the computer software and analyze the failure mechanism according to the results of simulation calculation. The numerical calculation method is widely used in geotechnical engineering. Especially in recent years, the mining area has developed rapidly, but there is a lack of long-term monitoring and control of the geological environment in the mining area, so the geological environment in the mining area has deteriorated sharply, and geological disasters occur frequently, which seriously threatens the safety of people in the mining area and the development of mining resources. There are serious geological disasters in the mining area. Moreover, the geological environment of Weibei limestone mining area is complex, which is affected by the external environment. With the continuous extension of open-pit mining, the stability of open-pit slope is more and more concerned by mining enterprises, and the potential safety problems caused by slope instability are more and more prominent. The Party Central Committee and the State Council attach great importance to the mine geological environment protection and management planning in Weibei area. It has many functions, such as regulating climate, conserving soil and water, and maintaining biodiversity. Weibei area in Shaanxi Province is the dividing line of climate between the north and south of China and an important ecological security barrier.
