Different Forms Of Protection For The Soil Slope Rainfall Infiltration Experiment Research

With the rapid development of expressway construction in China in recent years, government pay more and more attention to the research of ecological protection, but because our country starts late, ecological protection and vegetation restoration system is still far behind the demand of the actual project. It caused many problems of the construction of expressway engineering and seriously restricted the rapid development of expressway construction in China. In order to solve this difficult situation, the research of ecological protection and vegetation restoration system increased in our country. The ecological protection and related theoretical studies became the new trend of slope protection.As is known to all, heavy rainfall erosion and infiltration is frequently the main factor of slope instability. In this article, by way of indoor simulation experiment, the surface flow scouring the influence of infiltration to the stability of the slope was studied; First of all, in this article a lot of literatures were read to sums up the predecessors’ research on slope rainfall infiltration, and then three kinds of new type of ecological protections were put forward, namely:geotextile protective structure, the cement mortar protection, short tube protective structure, and introduces in details the structure of three kinds of protection and resistance to erosion mechanism. And then through the test apparatus were adopted to simulate the slope, and on the slope laid three kind of new form of protection, reuse erosion slope surface flow device, slope soil moisture content of the inner, according to the requirement for statistical data would use the proceeds and moisture content of drawing equipotential line, analysis and research of different forms of protective effect on the slope. Lastly, cement mortar protection field experiment was carried out, based on field test and verify the scour resistance of cement mortar protective effect of infiltration, and observe its effect on the growth of vegetation, has explored the construction technology of this kind of protection, in combination with other traditional protection, on the basis of construction technology, the construction technology of cement mortar protection and conditions, put forward reference for its application in future engineering.
