开发建设项目弃渣场设计及防洪问题

Issues on the Design of Dumping Sites and Flood Control of Development and Construction Projects

开发建设项目建设中,合理选取弃渣场,利用弃渣场弃渣是防止水土流失的重要环节,也是提高拦渣效率的重要保证。荒坡弃渣场设计应分析荒坡上加载弃渣后是否仍处于稳定状态,荒沟弃渣场设计应分析排水沟的泄洪能力,沟台地弃渣场挡渣墙与河滩弃渣场挡墙的设计应分析墙前冲刷深度。

In the construction of a development project, it is an important link to rationally select a dumping site and utilize the site for preventing soil and water loss and also a significant guarantee to increase the ratio of holding back the dumped materials. The design of slope dumping site should conduct analysis on whether the slope is still in stable statement after dumping. The design of gully dumping site should conduct analysis on flood discharge capability of drainage canals. The design of dumping site walls built in gullies and floodplains should consider the scouring depth of the wall.
