边坡开挖会导致边坡失稳，对交通等造成危害，因此要进行稳定性计算。-Slope excavation will lead to slope failure, traffic and other hazards, thus making the stability of the calculation.

采用非连续变形分析（DDA法）建立边坡模型，计算安全系数及模拟破环过程。(The slope model was established by discontinuous deformation analysis (DDA method), and the safety factor and simulated fracture process were calculated.)
