Research on Advanced Support Technology of Cutting Slopes Along the Expressway
The geological conditions in the mountainous areas of western Hubei are complex,the rain-fall is abundant,and the cutting slope is very prone to landslide during the construction.The ad-vanced support technology of the slope along the layer cut was studied in view of the different degrees of bedding collapse phenomenon during the excavation of the two slopes,based on the high slopes on the left and right sides of the exit of a high-speed tunnel in Enshi Tujia and Miao Autonomous Prefec-ture.According to the engineering geological conditions of the two slopes,the stability of the two slopes was evaluated and analyzed.The advanced support treatment scheme of anti-slip pile,and rail pile combined with anti-slip retaining wall was proposed.Through the comparative analysis of the two advanced support treatment schemes,it can be seen that the advanced support treatment scheme of anti-slip pile has more significant effect with lower costs and more environmental characteristics.
