摘要
泥流是泥石流的一种特殊类型,在黄土高原广为发育,陇西黄土高原祖厉河流域黄土泥流尤为发育。甘肃省道207线靖(远)-会(宁)段主要经过祖厉河两岸台地,多条泥流沟横穿省道207线汇入祖厉河。随着省道207线的升级改造,泥流的防控成为公路改建方案比选的主要控制指标。以祖厉河流域内苦子沟泥流为例,通过实地调查,分析该流域泥流灾害特点,推荐公路建设中的泥流综合防控方案。
The mudflow is a special type of debris flow and widely developed in the loess plateau. The loess mudflow is developed especially in the Zuli River Watershed of Longxi Loess Plateau. Jingyuan-Huining Section of Gansu Provincial Highway 207 mainly passes through the tablelands at both banks of Zuli River.Many mudflow channels cross the Provincial Highway 207 and run into Zuli River. With the upgrade reconstruction of this highway, the prevention control of mudflow becomes the main control index of comparing and selecting the highway reconstruction schemes. Taking the mudflow of Kuzi Ditch within the Zuli River Watershed as an example, the article analyzes the mudflow disaster characteristics of this watershed through the filed survey, and recommends the comprehensive prevention control scheme of mudflow for the highway construction.
