摘　　要：本文研究了浮体闸定位的工作原理,并在此基础上构建了浮体闸定位施工水力特性数学模型,给出基于水力特性研究模型的连续性方程、动力方程组及动能输运方程,对浮体闸定位中的阻力、流速分布及浮体闸剖面压强分布等进行数值模拟,得到吃水深度、转动速度以及水流速度等浮体闸的水力特性;对浮体闸转动阻力的影响因素进行了研究。并基于此得出浮体闸开启和关闭时对水体流速影响的变化规律。This paper studies the working principle of floating gate positioning,and on this basis,constructs a mathematical model of hydraulic characteristics of floating gate positioning construction.The continuity equation,dynamic equation group and kinetic energy transport equation based on the hydraulic characteristic research model are given.The resistance,velocity distribution and pressure distribution in the section of the floating body sluice in the positioning of the floating body sluice are numerically simulated,and the hydraulic characteristics of the floating body sluice such as draught,rotation speed and flow speed are obtained.The influence factors of floating body brake rotation resistance are studied.Based on this,the variation law of the influence of floating gate opening and closing on the water flow velocity is obtained.
