[Abstract]:Based on the summary of the present situation and common construction methods of high altitude tunnel, this paper looks up the relevant documents, explores the research means of construction scheme, summarizes the construction theory of high altitude tunnel, and then selects and introduces the evaluation method of construction plan. Finally, taking the Jiangluling tunnel on the highway between Gonghe and Yushu on National Road 214 as the engineering background, the construction scheme of the tunnel project in the high altitude area is studied by numerical simulation and Analytic hierarchy process (AHP). In order to obtain the most suitable for the high altitude area tunnel project construction plan. This article mainly from the following several aspects to carry out the following aspects to consult the relevant information extensively, summarizes the high altitude area tunnel engineering construction development present situation, the construction plan research method and the common construction plan, The theoretical support of the evaluation of tunnel construction project in the most high altitude area is the theoretical summary of the construction of the tunnel at high altitude. The basic concepts and construction characteristics of the tunnel at high altitude are introduced and classified according to the characteristics of permafrost and groundwater. This paper analyzes the mechanical characteristics of tunnel excavation, summarizes and introduces the construction procedure and flow chart of the tunnel construction plan in high altitude area, summarizes the evaluation standard of the construction scheme, and introduces the evaluation method of the construction plan. Including the theoretical foundation of numerical simulation and analytic hierarchy process (AHP), the operation flow and detailed evaluation step. 4. The selection principle of evaluation index of construction scheme is introduced and preliminary selection is carried out, and different construction schemes are modeled by numerical analysis method. By simulating the construction process and quantifying the evaluation index, the quantitative value 5 of different construction schemes is obtained. The evaluation method of the construction scheme selected in this paper is calculated by using a case, and the general engineering situation and design situation of Jiangluling tunnel are introduced. By using numerical simulation and analytic hierarchy process (AHP) to evaluate the construction scheme, the best construction scheme of 鈪，
