摘    要:在调查分析大量资料的基础上,提出了一种可不设镇静段的新型短廊道输水系统布置型式,并进行了水力计算和物理模型实验研究,研究成果表明:输水系统布置是合理的,各水力特征值满足规范和设计要求,达到了预期的设计目标。该输水系统型式既有集中输水系统工程量较省、施工方便的优点,又具有局部分散输水系统可降低初始波浪力、提高阀门初始开启速度、缩短输水时间及不设镇静段的优点,是一种适合中水头船闸性能较优的输水系统型式。

关 键 词:船闸  集中输水  镇静段  实验研究

Abstract:A new short-covert filling and emptying system without mitigative segment is put forward based on much data surveys and analyses.Hydraulic calculations and physical model tests are carried out.The study results indicate that the layout of lock filling and emptying system is reasonable and the hydraulic characters can fulfill the criterion and design demands.This type of lock filling and emptying system has many merits such as less work,convenient construction like end filling systems.It can also reduce the initial wave forces,raise the initial valve opening speed,shorten the filling and emptying time,and has no need for mitigative segment like part separate filling and emptying system.It is a fine type of filling and emptying system suitable for medium-head lock.
Keywords:shiplock  end filling and emptying  mitigative segment  experimental research
