摘　　要：针对锚固技术中锚固参数的选取对加固的稳定性与工程安全性的影响,以某电站通风兼安全洞断层围岩为例,采用SPSS统计分析软件对影响断层位移、应力、塑性区等指标的锚杆直径、锚固排距、锚杆长度等锚固参数进行敏感性分析,并进行了优化设计。运用有限差分软件FLAC3D的验算表明,优化后的锚固方案合理、有效,对工程建设具有一定指导意义。This paper focuses on the influence on the stability of the reinforcement and engineering safety,which is resulted from the anchor parameter selection.Taking the fault surrounding rock of a power plant ventilation and safety tunnel for an example,statistical analysis software SPSS is used to carry out sensitivity analysis about anchorage parameters（anchor diameter,anchor length,anchor row spacing）for influencing the indices such as fault displacement,stress and plastic zone.The optimization design of the anchorage scheme is verified by the finite difference software FLAC3 D.It shows that the optimization anchorage scheme is rational and efficient,which has guiding significance for engineering construction to some degree.
