- 摘要:
- 针对新昌县现有的供水管网系统，结合灵敏度分析方法和基于监测范围的分析方法，并根据实际工程情况，以最小化水力校核误差为目标，对新昌县供水管网的压力及流量监测点的优化布置方案进行研究，开发了服务于新昌县微观水力模型的监测点布置技术。同时，考察了监测点数量与位置对水力模型校核误差的影响，在充分利用原有监测点的原则下，最终确定了新昌县供水管网监测点布置方案。结果表明，校核误差随监测点数量的增加而减小，并在监测点数量达到一定值时不再降低，最终的流量、压力监测点布置方案实际应用效果良好，可满足工程需要。
- Abstract:
- Based on the actual engineering situation, the optimal layout of water supply network pressure and flow monitoring points in Xinchang County were explored by using sensitivity analysis method and monitoring range analysis method, and a monitoring point layout technology serving the micro hydraulic model of Xinchang County was developed to minimize the hydraulic calibration error. In addition, the influence of the number and location of monitoring points on the calibration error of the hydraulic model was investigated, and the monitoring point layout scheme of the water supply network in Xinchang County was eventually determined based on the principle of making full use of the original monitoring points. The calibration error decreased with the increase of the number of monitoring points until the number of monitoring points reached a certain value. The final flow and pressure monitoring point layout scheme had a good practical performance and met the need of the project.
