Experiment Of Performance Of Basis Material And Plant Furnishing For Ecology Protection Of Slope

A lot of cutting and embankment slopes produced by people. With a large number of highway construction, especially high-grade highways and mountain highway construction. Which result the destruction of the original landscape ecological balance of the soil vegetation system, lead to ground bared, soil erosion capacity reduced, soil erosion increased and ecological destructed. Thick basis material spraying Technology as one of rock slope vegetation technologies has been widely used in Chinese highway. The technology has broad application prospects, its core is the ratio of green basis material content. In this paper, drawing on the basis of previous studies for the green basis material, the author main did the following work:(1) The orthogonal method was adopted to study the compounding ratio of basis material through the testing in room. Then, through analyzing the testing data, the best compounding was obtained in the requirement of different time cycle, which is peat 20% , cement 5%, PAM 0.05%, insurance agent 0.15%, fiber 40%. Parallel test was did to study the pH value's variation rule, founding that both the basis material's pH value gradually close to neutral PH value. The two basis material one had plant while the other had no plant.(2) By the direct shear test of different proportions of basis material, finding that the sample's fiber content ratio should not exceed 25%, under certain fiber content , the maximum shear strength C of the sample is got at around the age of 14d of the cement.(3) Through the grass and shrub ratio model test, 1 to 2 most suitable Yichang Gorge Fanba highway construction's grass and shrub seeds ratios are obtained, which for the greening of Hubei central region. The result is got by analyzing plant seeds'sprouting rate, plant growth height and coverage.(4) Through the vegetation slope tests, the slope are greened by thick basis material technique, observing the plants'growth, the plants is under a certain ratio of grass and shrub seed, demonstrated the technical feasibility.
