Evalution And Analysis Of Typical Slope Of National Road 318 In Sichuan Province

318 State Line Road, about 1294 kilometers in Sichuan Province, through the many complex terrain, the number of the big size slope treatment project is much higher than other western regions. However, relatively few studies to summarize the areas along the slope engineering, it is not conducive to the promotion of existing disposal technology. Thus, the article with the support of Sichuan Road Slope Management System, analyzes and appraisal to the statistical induction of the typical slope’s engineering geological conditions、typical failure modes、slope characteristic factors and typical Reinforcement for measures along the road. Combining slope stability checking, we discussed the region’s typical of Slope technical suitability, the main research work is as follows:(1) Investigated the geological conditions along the 318 State Line Road, and comprehensive analysis of the topography, geological structure as well as the environment and climate, we proposed two typical areas in the study areas, namely:deep mountain gorge area and latent cut flat and hilly lands. At the same time pointed out the main difference of elevation, valley cutting, climate change and lithology, structure between the different topography.(2) with support of the Sichuan road slope Management System, Detailed information collected along the area 223 slope engineering, Determine the slope failure mode (collapse, landslide, scattered, collapse), slope characteristic factors (lithology, slope height, slope) and strengthening program (ie, retaining walls, pile, anchor, anchor) is three objects, analyzed relevant data collected, summed up the slope engineering of typical failure modes and targeted strengthening program along the road.(3)This paper choose the example of the K73 slope’s complete construction in Chengdu-Nanchong expressway, research the methods of typical rocky road slope construction monitoring in 318 State Line Road in the east of Sichuan Province in detail.(4) For the typical rock slope treatment engineer in Erlang mountain-Kangding K2794 along the State Road 318 in western Sichuan, using EMU rock slope processing software works on slope stability checking, analysis and evaluation of the suitability of the project strengthening measures.(5) Analysis the stability computations for the soil slope treatment engineers in Haizi mountain-Zhubalong K303 and the entrance of Pogo creek tunnel in the westen of Sichuan Province...
