1概述黄河防洪工程在遭受雨水冲刷时,常常引起工程坡面上的土壤流失,造成工程防洪能力减弱。对黄河防洪工程进行草皮栽植并管理养护,不仅可以绿化、美化黄河防洪工程;更重要的是保持草皮生长旺盛,提高草皮的固土护坡能力,可以提高堤身及坝身的抗雨水冲刷能力,对提高工程的防洪能力起着重要的作用。2黄河防洪工程被雨水冲刷的原因黄河防洪工程的设计边坡,河道工程土坡一般为1:2;堤防工程边坡坡度一般为1:3。工程在遭受雨水冲刷时,水土流失大都发生在堤坝边坡上,能引起工程坡面上的土壤流失,发生土壤 1 Overview The Yellow River Flood Control Project often causes soil erosion on the project slope when it is subjected to rainwater erosion, resulting in weakened flood control capacity. It is not only greening and beautifying the flood control project of the Yellow River, but also maintaining the strong growth of the turf and improving the capability of the earth and slope protection of the turf so as to improve the anti-rainwater scouring ability of the dam body and the dam body, It plays an important role in improving the flood control capability of the project. 2 Yellow River flood control project was washed out of the reasons for the Yellow River Flood Control Project Design slope, river construction slope is generally 1: 2; dike slope slope is generally 1: 3. When the project is subjected to rainwater erosion, most of the soil erosion occurs on the slope of the embankment, which can cause soil loss on the project slope and soil occurs
