摘要以城门洞型无压隧洞改建为引水发电隧洞的限裂配筋设计方法为研究对象，综合分析衬砌开裂前后围岩–衬砌混凝土–钢筋的联合作用，建立起二维(平面应变问题)非线性有限元数值仿真分析模型，经分析得到运行期内水压力工况下衬砌中钢筋应力、衬砌混凝土拉应力、衬砌裂缝、裂缝宽度的分布规律、衬砌配筋设计结果，以及检修期外水压力工况下衬砌混凝土裂缝处的应力集中现象和衬砌配筋的验算结果。提出的衬砌限裂配筋设计方法较以往的方法考虑更多影响配筋结果的因素，使结果更符合水工压力隧洞的实际工况，对同类工程设计具有指导意义。

Abstract：Taking the rectangular free-surface flow tunnel with arch crown to reconstruct into pressure hydropower tunnel as the object，the combined effects of surrounding rock，lining concrete and steel were synthetically analyzed when the lining cracks before and after occurring；a two-dimensional(plane strain) nonlinear finite element numerical simulation model was established. After that，the stress of steel，the stress of concrete，the regularities distribution of cracks，the crack width and the results of reinforcement design of the lining which is under the operation stage with internal water pressure conditions were got. Also，under the maintenance time with external water pressure conditions，the phenomenon of stress concentration of lining concrete cracks and the checking results of lining reinforcement were got. Compared with the previous methods the lining reinforcement design method proposed in this paper lead into more factors which may affects the reinforcement results，making the results much in line with the actual condition of the hydraulic pressure tunnel. It has guiding significance for similar engineering design.

Key words： tunnelling engineering pressure tunnel lining reinforcement numerical analysis lining cracks design by crack width control
