近年来,计算机在城市排水管理领域的应用,是业内人士不断探索的一个问题,GIS(地理信息系统)、MIS(管理信息系统)、EIS(专家信息系统)的开发和应用,为计算机在城市排水管理领域的应用开拓了广阔的前景。本文介绍计算机水力学模型(CHM)在城市排水管理中的应用。一、计算机水力学模型的建立建立排水管网计算机水力学模型包括:1.管网建模。主要依赖于精确的排水管网数据,如管道的管径、埋深、坡度、粗糙系数、节点地面标高和地理坐标、检查井尺寸和标高、管网边界条件等进行;
In recent years, the application of computer in the field of urban drainage management is one of the problems constantly explored by the industry. The development and application of GIS (geographic information system), MIS (management information system) and EIS (expert information system) Drainage management applications open up a broad prospect. This article describes the application of computerized hydraulics model (CHM) in urban drainage management. First, the establishment of computerized hydraulic model Establishment of drainage network Computer hydraulic model include: 1. Pipe network modeling. Mainly rely on accurate drainage network data, such as the pipe diameter, depth, slope, roughness coefficient, node ground elevation and geographic coordinates, inspection well size and elevation, pipe network boundary conditions, etc.;
