摘　　要：以弹塑性理论为基础,利用通用有限元分析软件ANSYS,通过数值模拟方式,分析岩溶隧道围岩及支护稳定性。重点从围岩应力、位移、塑性区角度探究既有隐伏溶洞对隧道围岩及支护稳定性影响。研究成果为隧道工程开挖及支护施工提供理论指导和技术支持。The stability of karst tunnel surrounding rocks and supporting is analyzed based on the elastoplastic theory and finite element analysis software ANSYS through numerical simulation. The influence of the existing hidden caverns on the surrounding rocks and the stability of support is discussed from the point of stress, displacement and plastic zone. The research results provide theoretical guidance and technical support for tunneling excavation and supporting construction.
