Description

Technical Field

[0002] Slope protection refers to the use of a series of engineering measures to protect the stability of soil or rock slopes to prevent geological disasters such as landslides and collapses caused by natural factors such as rainfall and earthquakes or human factors such as excavation and loading.

[0003] The existing slope protection measures mainly include skeleton protection and closed protection. Skeleton protection mainly includes arch skeleton slope protection, diamond skeleton slope protection, frame beam slope protection and window hole retaining wall. This type of protection structure has the advantages of small masonry protection area, large proportion of vegetation greening, and strong ability of vegetation recovery in the later stage. Its disadvantage is that the soft rock and soil in the skeleton or frame is prone to slippage, and the slope stability effect is poor. Closed protection mainly includes solid retaining wall, soil nail wall, retaining wall, shotcrete, etc. Although this type of protection structure has a good protection effect, it can effectively stabilize the slope for a long time. However, closed protection performs masonry protection on the entire slope surface, isolates the space for vegetation recovery, and cannot carry out later greening of the slope, resulting in extremely poor environmental protection and landscape effects.
