摘 要:船闸人字门门库布置关系到人字门启闭过程的局部水流结构及水体交换是否通畅,直接影响人字门启闭力及动水阻力矩的大小,对高水头大型船闸尤为重要。通过数学模型分析人字门启闭过程中的局部水流特征,论证门库各项边界条件对动水阻力矩的影响,进而提出高水头大型船闸人字门门库布置技术,给出科学合理的人字门门库体型及特征尺寸,可显著降低人字门启闭初期与末期的动水阻力矩峰值,从而解决高水头大型船闸人字门及启闭设备的设计难题,有利于人字门安全可靠运行。The arrangement of miter gate library of ship lock relates closely to the local flow structure and smoothness of water exchange during opening and closing of the miter gate.It directly affects the values of opening and closing force and the hydrodynamic resisting torque of the miter gate,and it's very important for the high-head and large-scale lock.This paper analyzes the characteristics of local flow structure during opening and closing of the miter gate by the mathematical model,demonstrates the influences of boundary conditions on the hydrodynamic resisting torque,and puts forward the arrangement technology of the miter gate library of the high-head and large-scale ship lock,gives a scientific and reasonable shape of miter gate library and the characteristic sizes,which can significantly reduce the initial and final peak value of the hydrodynamic resisting torque,so as to solve the design problems of the miter gate and hoisting equipment of the high-head and large-scale ship lock.It is beneficial for the miter gate to operate safely and reliably.
