摘　　要：采用三维有限元数值模型,分析圆梁山隧道高水压条件下衬砌结构受力及变形特征。研究结果表明,高水压对隧道衬砌结构影响显著,在高水压作用下衬砌结构的受力和变形都较大,衬砌结构上存在较大的纵向弯矩。水荷载是隧道衬砌结构的主要荷载之一,应引起足够的重视。The mechanical behavior and deformation characteristics of lining structure in Yuanliangshan tunnel under high water pressure was analyzed by using 3D finite element numerical model. The results show that high water pressure observably affects tunnel lining structure. High water pressure makes the internal force and deformation of lining structure increase. There is larger longitudinal bending moment in the lining structure. Water load is one of the main loads upon lining structure, which should be taken into adequate account.
