| Xinjiang has special environmental conditions,at the same time,the development of economic level,humans begin to encounter in the process of roadconstruction of high fill and deep excavation roadbed, so the stability of the slope become the important factor of road.Through field investigation and combined with experience in the design,the thesis that Xinjiang Hotan highway S216 line to cut some slopes Buya mine for the study,it analyzes the influencing factors about slope stability and establishes risk assessment system.By the method of laboratory tests,it obtains specific parameters of slope ground mass near the work site,And as a basis for follow-up data simulation.Binding set theory,with five-element connection number to analyze the state of slope static stability.Which using partial contact number and the set of potential analysises dynamic stability of slopes,and determins the slope control measures based on the analysis results.It calculats using finite element simulation, comparatives and analysises it before and after the change of slope treatment.Set pair analysis to accurately predict the development trend of slope stability using finite element analysis software, before and after the change of slope reinforcement,and based on the analysis results, combined with work experience to develop a reasonable slope reinforcement program.Taking S216 line of K60 + 100 ~ K60 + 180 sections of the excavation slope based on the background, considering the construction process of excavation slope stability condition, on the basis of set pair analysis to determine and measures, using the finite element analysis software on the slope reinforcement measures for research, analysis of the change of the slope stability before and after reinforcement, it is concluded that a more close to actual construction stage of excavation slope stability evaluation methods and reinforcement measures, for the future provide a more effective method in Xinjiang region slope problems. |
