Characteristic Analysis and Treatment Measures of a Certain Collapse in Langya Mountain Scenic Area of Anhui Province
[Purposes]This paper aims to analyze the characteristics of a collapse hazard point in Langya Mountain Scenic Area of Anhui Province and put forward the control measures.[Methods]By means of on-site investigation,topographic mapping,3D laser scanner,stability evaluation,etc.,the characteris-tics and stability of this collapse hazard are obtained.[Findings]This collapse hazard has the character-istic of toppling collapse,and all four main dangerous rock masses are in an unstable or understable state.[Conclusions]Treatment methods are used such as setting anchor rods,supporting walls,and cement slurry filling to reinforce the dangerous rock masses.And in addition,methods like manually removing loose stones,exerting the function of intercepting ditches are adopted so as to eliminate potential col-lapse hazard,and to ensure the safety and landscape value of the scenic spot.
