摘　　要：建立了隧道穿越断层破碎带的力学模型,根据所建立的力学模型,利用突变理论建立了耦合地下水、系统几何参数、介质刚度等因素的尖点突变模型来进行隧道穿越断层破碎带的稳定性突变分析,并建立了隧道穿越断层破碎带突发失稳的判据。A mechanical model was set up for the tunnel going through a fault fracture zone, based on which cusp catastrophe model was established by using catastrophe theory coupling with factors of underground water, system geometric parameters and medium stiffness, so as to analyze the catastrophe of stability for the tunnel going through a fault fracture zone. This also set a criterion for the disability of fault fracture zone with tunnel going through.
