| 摘 要： | 在分析以往几个水工钢筋混凝土隧洞衬砌裂缝计算通用模型局限性的基础上，根据力的平衡条件和变形相容条件，推导出了可以同时考虑围岩弹性抗力，配筋量，钢筋直径，钢筋表面形状等因素的裂缝计算通用模型。该模型适用于较大的水压范围，可以应用于不同断面，不同地质条件，不同内水压力，不同配筋情况的衬砌结构设计。

| Abstract: | Based on analyses of certain limitations of several universal models that had been used for calculatingcracks on the liner of hydraulic tunnels,a universal model for crack calculation which simultaneously takesaccount of elastic resistance of surrounding rocks,amount of reinforcement,diameter of reinforcing steel,surface pattern of reinfocing steel is established.This model fits in with a larger scope of hydraulic pressure,and can be used in the design of lined structures of different cross-sections,different geological conditions,different hydraulic pressures and different kinds of reinforcement. |
