SNS flexible protection applies to building facilities near the buffer zone of high mountains, the rock fall, flying rocks, avalanches, mudslides blocked from building facilities to avoid the disaster destroyed the common specifications for building facilities: SNS flexible protection openness of the system, allows freedom of groundwater drainage, slope instability problem is avoided because of increased pressure caused by groundwater; SNS flexible protection system in addition to a certain contribution to the stability of the slope, the slope suffered while inhibition further weathering and erosion, and on the slope morphology no special requirements, do not destroy and change the slope of the original topography and vegetation growth conditions, features open SNS flexible protection system to subsequent or conditional and artificial slope in the future when needed Green faces retain the necessary conditions, enabling free growth of green plants in the SNS flexible protection and open space, the role of the solid earth and slope protection plant root system became one, thus inhibiting the slope destruction and soil erosion, which in turn protecting the topography and slope vegetation, slope protection and to achieve the best environmental purposes.
