闸门水力特性综述

Summarization of Hydraulic Characteristic of the Sluice Gate

闸门在动水关闭的过程中所承受的动水压力是设计人员十分关注的重要问题。动水压力包括门顶水柱压力、下吸力、上托力、支承和止水摩阻力等,这些作用力,均是确定闸门启闭容量的重要依据。如果考虑不当则有可能无法打开或关死闸门。

The pressure supported by the entrance speedy accident sluice-gate in the process of closing the dynamic hydraulic pressure is the problem the designers pay close attention to. The dynamic hydraulic pressure includes water column pressure, down-suction force, up-holding force, sustaining force and friction. All these forces are important foundations in determining the capacity of opening and closing the sluice gate. If not properly considered, the sluice gate may not be opened or closed.
