摘　　要：在工程施工中,边坡失稳是造成一系列事故灾害的主要原因。需预先对现场的边坡进行稳定性分析,提前3D发现危险,以采取预防加固措施,避免事故伤害的发生。采用ANSYS软件建立边坡大模型,利用FLAC进行边坡数值模拟计算。根据边坡岩土结构实际物理性质,最大化地模拟边坡现场实际地质情况,利用软件内嵌的强度折减法分析计算现场边坡的安全状态,并提出边坡加固措施。该应对措施可以为同类型边坡防护工作提供参考价值,以较低的工程成本完成边坡安全防护。In engineering construction,slope instability is the main cause of a series of accident disasters.Conducting a stability analysis of the on-site slope in advance can help to detect potential dangers early,take preventive and reinforcement measures in advance,and avoid the occurrence of accidents and injuries.This article uses the ANSYS software to establish a large slope model,and FLAC^(3D)for numerical simulation calculations of the slope.According to the actual physical properties of the slope's geotechnical structure,the actual geological conditions of the slope site are simulated to the greatest extent.The strength reduction method embedded in the software is used to analyze and calculate the safety status of the on-site slope,and slope reinforcement measures are proposed.These countermeasures can provide reference value for slope protection work of the same type,and complete slope safety protection at a relatively low engineering cost.
