排水管道内沉积物沉积模拟与分析研究

Simulation & Analysis of Sediment Deposition in Drain Pipe

排水管道内沉积物对城市排水系统的正常运行、城市河道的水体质量等均有较大影响。受技术条件的限制,部分排水管道尚难实现内部沉积物堆积情况的长期持续性监测分析。在本项目中,以某大型排水系统排水干管为研究对象,利用Infoworks CS等计算机水力模型软件,通过水质模型技术,分析研究不同时段、不同区域管段、不同水力条件下管道沉积物的堆积情况,并对模型的模拟结果进行函数拟合。研究内容拓宽管道沉积物研究的技术思路和手段,也为排水行业技术管理人员提供借鉴与参考。

The sediments in drain system have a greater impact on the operation of urban drainage system and urban river water quality. Limited to technical condition s, long- term continuous monitoring & analysis on the inner sediment accumulation in some drains are difficult to be realized. In this project, taking some large scale drain system's drain pipe for example, using Infoworks CS to study & analyze the sediment deposition different time, different regions, and different hydraulic conditions through water quality model technique, and fitting the simulated results from the model. The research can widen the technical ideas and means to the sediment study, which also provide references for the technical management personnel of drainage industry.
