Exploration and Support Design of High and Steep Slope Based on 3D Laser Scanning
Based on the complex high and steep slopes project of the Silver Lake Cty,3D laser scanning technology is adopted to identify the spatial spreading pattern of slopes,the spatial distribution of dominant of the characteristic structural surfaces,which provides a basis for the design of slopes.Based on the investigation of 3D laser scanning and the results of slope stability evaluation,for the excavated soil-rock combination of high slopes,the upper soil body adopts"slope release+anchor lattice beams",and the middle and lower rock body adopts"slope cutting+Mado stone wall"as the management measures,and for the fill slope,it adopts"strong tamping reinforcement".For the fill slope,the management measure of"strong tamping reinforcement,vertical support of buttress type or gravity type retaining wall,reinforced soil at slope rate and slurry masonry lattice girder protection at slope face"is adopted,which has good ecological restoration effect and remarkable economic benefit.
