摘　　要：为研究窄缝挑夫水力特性,利用数值模拟技术,结合具体工程实例,通过对曲面贴角体窄缝式挑坎内压力特性、流速分布及挑射水舌形态等水力参数进行计算分析,提取了物理模型无法获得的较为详细的流场信息。该计算结果能够为类似工程起到一定指导作用。By using numerical simulation, the hydraulic parameters inclusive of pressure characteristic, velocity dis-tribution and nappe form in slit-type flip bucket with curved surface were calculated and analyzed. What＇ s more, detailed information of flow field which cannot be acquired from physical models were obtained. This research serves as a guide for similar engineering.
