阶梯式跌水工程应用于山地城市排水系统

摘要

Due to the complex landscape of mountainous city, there's a big height difference in lower drainage system from the water outlet of rainwater drainage system, so reasonable selection of water drop energy dissipater is the key part of the study on steep slope drop of the drainage system in moun-tainous city. By introducing the flow pattern and technique calculation of step torrent gutter in mountainous city and analyzing practical cases combined with theories, this paper can offer some references for similar projects.%由于山地城市地形复杂，雨水系统出水口接入下游排水系统时面临大高差陡坡，合理选择跌水消能工是山地城市排水系统陡坡跌水研究的重点。通过介绍山地城市阶梯急流槽水流流态及工艺计算，并结合理论及案例进行了分析，为山地城市排水系统跌水消能设计研究提供参考。
