Carbonaceous Shale Slope Of Eco-technology Firm Research

Domestic carbonaceous shale slope protection has been researched for a great deal of times. But the current widespread use of carbonaceous shale of hanging sprayed concrete, mortar rubble slope protection and closed bolt and cable slope, so even though it can form an effective protection of the slope, but which is far away from the concept of environmental protection falls of highway; and some of carbonaceous shale for ecological protection is biased towards the growth of vegetation and landscape effects, ignoring the shallow slope stability. This paper based on highway of Liuzhai to Yizhou in Guangxi, which for carbonaceous shale shallow slope stability and ecological slope protection to do as following:(1) Two different indoor collapse under test are carried on in order to research the carbonaceous shale slope engineering properties of carbonaceous shale, which can find the main factors of the properties of carbonaceous shale disintegration ,and talk about the relationship among the mechanism of disintegration of shale, disintegration and cycles of collapse characteristics.(2) Evaluations are made through the test of polymer modification on the effect of carbonaceous shale.(3) The stress field, strain field, displacement field and other parameters in the excavation of a slope were analyzed using FLAC3D computing software, in order to study the classification of slope stability before and after excavation.(4) Acrylic emulsion adhesive of carbonaceous shale can be used as slope protection for its good water resistance, which proved through polymer modification effect of curing agent was found that and. Four different forms on-site carbon loose shale deposits of the test polymer are test, and modification of their effects and mechanism of modification are carried on. The curing agent is mixed by test which suitable for protective carbonaceous shale in the slope.(5) For cured carbonaceous shale slope, vegetation protection, use the appropriate mix spray sowing and the corresponding construction process on carbonaceous shale slope protection.
