摘　　要：随着大型水利水电工程导流洞进口孔口尺寸变大、挡水水头变高,平面闸门门槽承受的推力也相应变大,对混凝土结构安全运行的要求越来越高。文章结合中国导流洞进口平面门槽结构运行条件,采用规范方法和有限元方法对门槽混凝土结构的受力和变形进行了对比计算分析,提出了门槽混凝土结构的破坏形式、受力特征、变形方式、裂缝开展方向以及配筋方案,为今后大断面、高水头导流洞进水口平面门门槽结构的设计提供借鉴。With increase of inlet size and water pressure of diversion tunnel of the large-scaled hydropower projects, the thrust to be borne by the plane gate slot is increasing accordingly. Furthermore, the safe operation of the concrete structure is required highly. Combined with the operating conditions of the plane gate slot structure at inlet of the diversion tunnel and by application of the methods in the specification and the finite element method, stress and deformation of the concrete structure of the gate slot are compared, raising the failure form, action char- acteristics, deformation mode, crack developing direction and reinforcement arrangement scheme of the concrete structure the gate slot. It provides design of the structure of the gate slot at inlet of the diversion tunnel with large section and high head with a reference.
