Performance Of Vegetation-growing Concrete Plate Wall Inslope Support Analysis

Traditional side slope supporting structure for slope reinforcement simply from the angle of slope stability, ignoring the requirements of ecological restoration in slope, coagulation concrete slope protection technique for slope vegetation ecological restoration, ignored vegetation-growing concrete strength properties, does not apply to less stable slopes. This paper concrete plate wall supporting structure of vegetation through vegetation-growing concrete for slope reinforcement of support structure, with a view to expanding the scope of application of concrete slope protection technology of vegetation.This subject through vegetation-growing concrete strength test research vegetation-growing concrete of tie than design, and preparation method and strength characteristics; using limited difference software FLAC-3D established slope vegetation-growing concrete plate wall support nursing model, analysis slope in not support nursing, and vegetation-growing concrete plate wall support nursing and General concrete plate wall support nursing of slope deformation and stability changes law, through single factors control method research vegetation-growing concrete capacity heavy, and vegetation-growing concrete modulus, and plate wall thicknesses and anchor parameter influence on deformation and slope stability; on preliminary study on the design methods of vegetation-growing concrete plate wall. Specific achievements are as follows:(1)Volume method of concrete mix design using units of vegetation, for the purpose of controlling the porosity, vegetation-growing concrete mixing split-feed mixing and extended mixing time, the vegetation-growing concrete porosity prepared to meet target voids requirement(2)Vegetation-growing concrete strength with the goal of decreased porosity and voids is 25% vegetation-growing concrete goals, 28 day compressive strength compressive strength of plain concrete C25 can be achieved to meet strength requirements of support structure;(3)Slope under the vegetation-growing concrete plate wall supporting, slope displacement reduced slope significantly improved, to meet the engineering requirements, but the effect is lower than normal strength concrete slab walls;(4)the vegetation-growing concrete tolerance interral, elastic modulus, and anchor the prestressed concrete, the side slope deformation and stability of the affected laws, as well as affected side slope deformation, and slope stability of the key factors in the vegetation-growing plate concrete wall support structure design parameters reasonable value range;(5)Introduces the vegetation-growing concrete plate wall supporting structure of the support mechanism, theory and promote the calculation method of slope displacement and slope safety factor, provides the reference for the design of supporting structure of vegetation-growing concrete plate wall.
