摘要
通过引入地理信息系统(GIS)技术,以街区作为管段沿线流量的计算单位,考虑街区面积、人口密度、街区内部大用户用水量等各项因素,改进了给水管网的计算.结果表明:GIS技术可使整个给水系统工作状况更接近实际.
To aid technology transfer of water-distribution system optimizers, a computer-aided support system is developed which integrates a Geographic Information System for spatial database management and analysis with hydraulics. The primary achievement of this software that it developed a new method to calculate node-flux and the along the line flux which considers the influence of the variety of different blocks.
