河道项目主体工程选址的水土保持评价分析

Evaluation and Analysis on Water and Soil Conservation of Main Works of a River Project

对主体工程选址进行评价是水土保持编制的一个重要内容,是水土保持措施设计的基础。某河道综合治理段长5.62 km,由河道治理工程、生态景观工程和建筑物工程等组成。河道淤积严重,断面变化较大,且河道两岸多为土质岸坡,抗冲刷能力差,因此,对项目主体工程选址尤为重要。文章按国家标准和有关文件对主体工程选址进行了水土保持分析与评价。

The evaluation of the site selection of the main works is an important content of the compilation of water and soil conservation, and is the basis for the design of water and soil conservation measures. The comprehensive regulation section of a river is 5.62 km long, which is composed of river regulation works, ecological landscape works and building works. The river channel is seriously silted, the section changes greatly, and the two banks of the river channel are mostly soil bank slopes, which have poor anti scouring ability. Therefore, the site selection of the main project is particularly important. This paper analyzes and evaluates the water and soil conservation of the site selection of the main project according to the national standards and relevant documents.
