瓯飞一期围垦工程通航孔设计研究

Navigable Hole Design Research of Oufei First Phase Reclamation Project

常规通航建筑物在设计中多半采用船闸、升船机。而作为直接可以平水通航的出海通航水闸,其水流特性、布置形式等研究在浙江省乃至全国也不多。以瓯飞一期围垦工程为背景,结合通航孔模型试验以及数模计算成果,主要从水力学角度对通航孔平面位置、口门形式、导航墩墩头形式、泄洪时的水力学特征、水闸对通航孔布置的影响等方面进行探讨,并参考已建东海塘通航孔和金清新闸通航孔,提出导航墩长度和结构的设计优化,分析出通航孔设计的一些基本原则。

In the design of conventional navigation structures , locks and ship lifts are mainly used . Sea navigation locks can directly navigate through water level , and the study of its flow characteristics and layout form , and so on , are relatively uncommon both in Zhejiang province and China . Take Oufei first phase reclamation project as the background , combined with navigable hole model experiment and numerical simulation results , mainly probe navigable hole plane position , entrance forms , navigation pier head form ,flood water hydraulics characteristics , sluice’ s impaction on navigation hole layout , and so on , from the perspective of hydraulics . Refer to east seawall navigable hole and Jinqing new brake navigable hole both of which have been built , propose the design optimization of navigable pier length and structure , analyze some basic principles of navigation hole design ,its achievement can provide reference for similar projects .
