Description
Technical field
The present invention relates to hazards control technical field, more particularly to a kind of Rolling Stone impact in-site modeling test dress
Put.
Background technology
In geological disaster, landslide, avalanche, mud-rock flow can cause serious damage to public roadbed, and project post-evaluation is usually
The measure taken is slope protection and retaining structure protection.Slope protection has mortar or tabia etc. to wipe one's face, whitewash, spray coagulation
Soil, mortar flag stone revetment, shotcrete bank protection, anchor and spray net bank protection etc..Such measures are mainly used to the rock for protecting excavation slope domatic
Weathering off, it is broken fall and the phenomenon such as a small amount of falling rocks chip off-falling.The side slope protected, should have enough stability, for unstable
Side slope then first supporting and retaining system is protected again.Retaining structure type of protection is more, such as retaining wall, anchored bolt retaining wall, friction pile.These supporting and retaining systems
The existing protective action of structure, plays the role of to reinforce slopes again.It is often undue to pursue intensity effect using engineering measure bank protection, break
Be broken ecological natural, landscape effect is poor, and over time, concrete surface, mortar flag stone face can weathering, aging, very
To damaging, later stage regulation is costly.
Another big geological disaster after landslide, avalanche, mud-rock flow is the Rolling Stone in side slope.Rolling Stone is on China mountain
Area, particularly western mountainous areas Highways ' is seen everywhere, and distribution is extremely wide, and its generation is unexpected, frequency is high, hard to guard against, right
The various highway structures such as highway pavement, bridge, tunnel's entrance and exit, open cut tunnel, hangar tunnel and driving vehicle, passing crowd are caused sternly
The threat of weight.
Nowadays the control structure to Rolling Stone mainly has：Active protecting net, passive protection net, Rolling Stone canopy, Rolling Stone barricade etc.
Prophylactico-therapeutic measures.Use Rolling Stone canopy safeguard structure to anti-Zhiduo County of Rolling Stone for Important Sections, the structure can prevent and treat Rolling Stone road pavement,
The destruction of the important engineering such as bridge floor, tunnel's entrance and exit, but, nonetheless, due to the unpredictability of rolling stone impact force, such as
The impact velocity of Rolling Stone, Rolling Stone weight, Rolling Stone projected angle of impact are not quite similar, and Rolling Stone boron is also difficult under fully effective stop at a high speed
The Rolling Stone impact for falling.
