Study On The Experiment And Mechanism Of The Vegetation-slope-protection On The Expressway Rock Slope In The Condition Of Incomplete Close

The stability of the slope concerns the security run in the expressway, the traditional slope-engineering can better settle the stability problem of the slope, but it has destroyed the ecological environment. With the constant enhancement of people's environmental consciousness , we must protect the peripheral ecological environment while we are in engineering construction.In recent years, such as littering slope-engineering, plant and grow vegetation slope-engineering, hydraulic sow slope-engineering , three-dimensional vegetation slope-engineering, dig vegetation slope-engineering etc receive fast application. Because the such technology ensure slope stability while resume ecological environment where engineering construction destroied , therefore these new-type technology receives extensive commendation once appearing.Compared with traditional technology, these vegetation slope-engineering is a material difference: That it is different from wiping surfacing, whitewashing, gushing out concrete , thick liquid build blocks of stone protect wall, hang net-whitewashing slope protection ,etc. traditional slope protection way, tight in whom slope sealed dense very much; Different from such as retaining wall , resisting slip pegs, long stock,etc., let some of slope totally expose among the air. It is a slope-engineering way that cover the slope by vegetation under the condition of incomplete close station. Because while the vegetation slope separate the outside, it exchange some substance such as moisture , heat, mineral substance, nourishment ,etc; so we include it as a slope-protection of incomplete close station distinguished from the traditional slope-protection way , there are a lot of advantages using vegetation of slope-protection in suit side such as .the small project amount, needn't do the auxiliary project, the project material is local soil , grass seed , a small amount of cement and other additive, economize resources, and nearly free from contamination; It can adjust the ecological balance along the line, it will not produce " the tropical island effect"; The fabrication cost of the project is low, and the length of service is long. It can remedy the defects product by the past project. The present incomplete sealed slope-protection way rely mainly on vegetation slope-protection totally, with the development of...
