船闸输水系统数据库软件与引航道非恒定流实时模拟

Database software of shiplock′s filling and emptying system and real-time simulation of unsteady flow in approach channel

运用面向对象开发工具及地理信息系统(GIS)技术,开发了图形显示与属性查询有机结合的船闸输水系统数据库软件,并介绍了软件功能.结合三维GIS与数学模型计算结果,对泗阳船闸泄水时下游引航道非恒定流进行了实时模拟,可同时查询流场内各点属性、地形信息等,有助于研究人员的分析判断.

A database software of the shiplock′s filling and emptying system which combines image display and attribute search is developed by using the Object Oriented technology and GIS, and functions of the software are presented. Real-time simulation of unsteady flow in the downstream approach channel of Siyang Lock is carried out based on the three-dimensional GIS and calculation results of a mathematical model. Attributes of the flow field and landform information can be searched quickly at the same time.
