Evaluation of Four Kinds of Water and Soil Conservation Measures on Highway Side Slope

Abstract:

Four kinds of protective measures and three contrast measures were chosen on Harbin-Suifenhe highway to analyze the effects of different types of soil and water conservation measure on highway side slope soil. The results showed that Soil and water conservation measures of highway side slope increased water holding capacity and soil conservation capacity significantly. The saturated water holding capacity, capillary water holding capacity and field water holding capacity of E, PP grid measure were 1.79 times,1.60 times and 1.62 times respectively of that in contrast 1 measure. E, PP grid measure, resin network measure and spread planting measures reduced runoff 58.5%, 59.3% and 50.8% compared with contrast measures. Consider of landscape and cost factors, spread planting measures was recommended to use on the smaller slope degree of highway side, E, PP grid measure, resin network measure were recommended to be used on the steep slope of highway side, hex hollow brick measure was not recommended.
