摘　　要：鱼骨坝工程是鱼嘴工程中较为典型的布置形式。通过结合水槽概化实验和二维水流数值计算成果,研究了鱼骨坝的水位、流速、流场和动水压强等水力特性,并对水毁原因进行了分析。研究成果对鱼骨坝工程设计具有一定的理论价值。Fish-bone type dividing dike is a typical layout in the fish mouth type dividing dike.Combining with the results of flume generalized test and 2-D mathematic model,hydraulic characteristics of fish-bone type dividing dike including water level,flow speed,flow field and dynamic pressure,etc.,is carried out,and the reason of flood damage is analyzed.The conclusions will contribute to design of fish-bone type dividing dike.
