云南山区高速公路沟谷型弃渣场洪水影响评价方法研究

Study on Flood Impact Assessment Method of Highway Cheuch-type Spoil Site in Yunnan Mountain Area

以会泽—巧家高速公路腰店子沟弃渣场为例,研究云南山区高速公路的弃渣场洪水影响评价,对弃渣场的防洪标准、暴雨洪水特征、河道演变进行分析,通过河道特征值量算、洪水计算、过流能力计算、雍水计算、冲刷分析等研究得出洪评结论,为弃渣场的设计、施工、管理提供指导。同时可为同地区的其他弃渣场的规划建设提供参考与借鉴。

Taking Yaodianzi Spoil Site in Huize-Qiaojia Expressway as an example,the flood impact assessment of spoil site in the mountainous area expressway in Yunnan is studied.The flood control standard,rainstorm flood characteristics and river course evolvement of spoil site are analyzed.The flood assessment conclusions are given through the river characteristic value calculation,flood calculation,discharge capacity calculation,backwater calculation and scouring analysis,which provides the guidance for the design,construction and management of spoil sites,and can also be referred for the planning construction of the other spoil sites in the same region.
