Passenger Grass-Shrub And Joint Framework Protection And Engineering Application

Subgrade slope is defined as part of the embankment slope on both sides in order to prevent water erosion, and to ensure embankment stability, take masonry and shotcrete slope, planting, etc. for protection and reinforcement of the slope. Slope protection works are divided into two major categories of protection and ecological protection. Simple engineering protection, not only lead to destruction of the plant is not restored, slope are not in harmony with the natural environment, the lack of beauty, but also produce light noise pollution, or even destroy the surrounding environment. In recent years, slope engineering will be more and more, taking into account environmental considerations. In this paper, the East Central Railway of Hainan inter-city express passenger line as the background slope in the coastal areas of strong typhoons, heavy rain conditions, protection and ecological protection works a combination of both the word grass shrub skeletons comprehensive protection of the Applied Research. Through the development of slope protection at home and abroad, and domestic like a typical subgrade slope protection engineering of the successful experience of comparison, from the embankment side slope stability and slope protection in the form of roadbed, slope, etc. The mechanism of plant protection research, put forward that Hainan East Central Railway Passenger Dedicated Line Grass shrub skeletons comprehensive protection herringbone design and green program, the following conclusions:(1) Slope protection should be based on eco-green for the direction of the slope stability is to maximize the use of plant protection methods. Grass, shrub mixed green protection, can play fast grass covered slope, to reduce the role of erosion, and the growth of shrubs to provide a good temperature and humidity environment, maximize the use of native plants, can increase the survival rate of grass and shrub, to long-term and stable slope effect.(2) For plant protection alone can not guarantee stability of the slope, cut-off water should be combined with the word skeleton, anchor frame beam slope protection works within the shrub-grass protection methods, such as grass and shrub joint framework to comprehensive protection measures to be green on the slope.(3) The heavy rainfall may produce a strong subgrade slope erosion effects, the finite element software ANSYS, discussed the skeleton structure and suspended in normal use force under the circumstances, the results indicate limbo under the framework vulnerable to damage.(4)Slope protection settings can be weakened skeleton runoff erosion ability, strong typhoons, heavy rainfall areas may be appropriate when using skeleton slope lower support frame spacing, in order to increase the slope of the anti-erosion ability.(5)Using finite element analysis software ANSYS, on the embankment slope distribution of the wind study, analysis of strong typhoons is the slope of the embankment, particularly the impact of plants, grass and shrub combination of utilizing a good slope slope effect.(6)Coastal areas with high vegetation cover, rainfall abundant, the trees along the route such as shelter materials can greatly reduce the role of wind on the slope of plants, on-site observation also proved this point.(7)Green Line should pay attention to daily maintenance work, to comply with "Railway Forest Management Rules" to ensure that railway traffic safety and operations.
