Description

Vegetation side slope scouring-resistance Journal of Sex Research device and experimental method
Technical field
The present invention relates to side slope technical field, especially a kind of vegetation side slope scouring-resistance Journal of Sex Research device and experimental method.
Background technique
China mountainous region area accounts for the 33.3% of national territorial area, and Landslide Hazards take place frequently.Rainfall is common the luring on mountainous region landslide One of inducement element.Some researches show that 60% or more slope instability is due to caused by rainfall.In recent years, heavy rainfall, heavy rain are more Secondary attack China partial region, causes many geological disasters, has seriously threatened the people's lives and property safety.China's engineering A large amount of exposed engineering slope is formd in construction, destroys the ecoscape in region, while also resulting in soil and being largely lost And degeneration.From the point of view of the application study of current Technology of Slope Protection by Vegetation, mainly around preventing hillside fields from the mesh of rain erosion And progress, it is by effective covering to slope surface and protects surface soil in time, protects it from surface erosion and soil degradation; Soil is held by root system of plant, reduces interstices of soil hydraulic pressure, to reinforce soil layer and improve skid resistance.It is directed to vegetation side slope at present The research of scour resistance is primarily directed to vegetation side slope root --- and the shearing strength or anti-impact flow velocity of native complex are reversed between coming It reflects, data can not directly and comprehensively reflect the erosion resistibility of vegetation side slope.Furthermore it is one since side slope soil washes away and has The systematic procedure of globality and comprehensive effect, factor effect and effect relation are extremely complex, so at present about erosion quantity Counting statistics model there are more or less deficiency, the math equation of foundation also tend to it is more complicated, be not only not easy to research and Statistics, the convincingness of calculated result are also limited.About side slope model, existing model be concentrated mainly on stability of slope Journal of Sex Research and In the research and development of bulkhead tech, and Most models are concrete structures, and inconvenience is adjusted flexibly the impact factors such as the gradient, slope aspect, grinds It is more narrow to study carefully face.Currently the laboratory experiment model for specializing in vegetation side slope scouring-resistance is had no, for this purpose, providing a kind of special It studies vegetation side slope scouring-resistance laboratory experiment model and rigorous experimental method is that those skilled in the art is urgently to be resolved Problem.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of vegetation side slope scouring-resistance Journal of Sex Research device and experimental method, The topography and landform character and soil characteristic on ground to be restored are reduced using natural method is intended, with the matter for the soil being washed Measure measurement index as vegetation side slope scouring-resistance, can more comprehensive quantitatively evaluating vegetation side slope scouring-resistance performance, it is right In slope vegetation restoration there is important theoretical research and technological guidance to be worth.
In order to solve the above technical problems, the technical scheme adopted by the invention is that: a kind of vegetation side slope scouring-resistance Journal of Sex Research Device, including hydraulic lifting side slope model slidably connect at least on the liftable slope panel of hydraulic lifting side slope model One uncovered substrate case, uncovered substrate case include bottom plate, and for placing quasi- natural slope strata model, uncovered substrate case leans on bottom plate The side panel of nearly hydraulic lifting side slope model rotating side is detachable slidingtype side plate, hydraulic lifting side slope model side It is placed with the muddy water collecting box matched with uncovered substrate case, uncovered substrate upper box part is hung with artificial rain device, detachably The width of slidingtype side plate is matched with the height of soil base material layer.
