Study Of Straw-net Technology For Ecological Slope Protection

With the large scale emergence of highway, water conservancy and railway in our country, more and more slopes engineering produced and the technologies of slope-protection get a huge improve. The technologies for ecological protection become a trend in current development as the public attention to ecological environment the official extension and demand to green circular economy. Higher standard to technologies in slope protection raised make it satisfied the requirement of slope stabilization and ecological-environment protection. However, the current ecological slope protection has some defect in material of choice and price. This thesis, taking the Straw-net which is a new ecological protection as the research object, gives a systematic analysis of basic law of the slope protection to straw-net and it’s slope scour, matching construction technology, combined with hydraulics, soil mechanics and principles of sediment movement mechanics. The main contents focused in the following aspects:(1) It summarizes the different types and its characteristics of ecological slope, and its destructional forms by rainfall erosion. Finding the physical property paraments, method for making and protection mechanism of straw-net.(2) Determining the erosion law of straw-net’s diameter and spacing for the soil erosion capacity through establishing the rainfall erosion model, simulating the slope rainfall erosion experiment. Confirming the raw of straw-net protection to the slope flow rate by simulating the slope runoff test.(3) Verifying the actual effect of straw-net ecological slope protection, the corrosion of straw-net and the growth of grasses through field test. Analyzing the effect law of protective form to the growth regularity of glasses.(4) Comparative analyzing different technologies of slop protection with vegetation, obtaining the construction technologies corresponding straw-net protection, and detailing construction process scheme...
