Research on the Ecological Protection Mechanism and Applied of Expansive Soil Slope

This paper summarizes and analyzes the basic concepts and ecological protection mechanism for expansion geotechnical slope failure mechanism and the resulting impact on the shallow, traction engineering properties such as analysis, proposed ecological slope of expansive soil slope mechanism of action: vegetation system by improving internal slope soil moisture and temperature changes affect the atmosphere and thus effectively reduce the depth. Vegetation root through reinforced anchoring, delay time and improving soil hydration ductility such as the role played good strength enhancement. Vegetation formation can effectively improve the damaged outer slope interface morphology, to restore the ecological environment and landscape effect. Integrating the past experience on expansive soil slope treatment, this paper provide a slope treatment method used in Nanning metro Tunli section, these will provide reference for the expansive soil slope ecological management.

In this paper, a technology of ecological slope protection with aqueous polymer soil stabilizers is introduced. A clayey soil slope located in the Nanjing Pukou area in China is taken as a test field and a kind of aqueous polymer soil stabilizer, namely STW, are used. STW is developed by the research group of authors. The test field is divided into four regions based on the slope gradient, and one of regions, as a contrasting area, is no any soil stabilizer. The implementing process of this technology is also presented. The field test indicates that STW polymer soil stabilizer are very effective for improving the water-stability and anti-erosion of the soil slope and promoting the vegetation growth on the slope and is worth popularizing for water-soil prevention in the slope areas due to its simple implementation, low cost and ecological protection effect. Finally, the ecological slope protection mechanism of the aqueous polymer soil stabilizers is discussed.

Bolt Support

In the expansive soil steep slope treatment, research and generalize FRP materials anchor bolt instead of steel anchor bolt. Selected appropriate expansive soil slope on the premise of comparability .Made FRP bolt and steel bolt contrast test formulation. The two types of anchor, stress, displacement, crack, ultimate bearing capacity test results contrast were analysed. It is concluded that the total effect of the four aspects of two kinds of bolt support is almost. But from the perspectives of durability, taken together, should change the traditional slope supporting methods, and the FRP bolt faster and more widely used in the expansive soil slope supporting.
