[Abstract]:The South-to-North Water transfer Project is a major trans-basin water transfer project planned and implemented in China in recent years. The Yellow River Tunnel Project is the key building for the South-to-North Water transfer Project to cross the Yellow River. The tunnel is mainly composed of saturated medium and fine sand silty loam and half sand and half soil. The hydrogeological conditions are complicated and the technical requirements are high. In addition, the middle line through the Yellow River tunnel has the characteristics of large diameter and long distance, it belongs to the large water conveyance tunnel project, the groundwater pressure is high, and the construction equipment and construction technology of the tunnel are required to be higher. Therefore, it is of great reference value for the construction risk management and control of the Yellow River Tunnel to carry out the risk evaluation study of the middle route of the South-to-North Water transfer Project through the Yellow River Tunnel. Based on the project of the Yellow River Tunnel in the middle line of South-to-North Water transfer Project and the actual situation of the project, the risk assessment of the construction of the tunnel through the Yellow River in the middle line of the South-to-North Water transfer Project is studied by using the analytic hierarchy process and grey theory. This paper discusses the research background and significance of the subject, the research status of underwater tunnel construction risk assessment at home and abroad, as well as the research methods and main contents of the paper. The basic theory and method of risk analysis are expounded, and the risk assessment model of underwater tunnel construction is constructed. Taking the actual project as an example, this paper expounds the general situation, construction mode, tunnel section type and engineering characteristics of the Yellow River Tunnel in the middle route of the South-to-North Water transfer Project. Risk factor identification and risk evaluation index system are used to identify the construction risk of the middle line of the South-to-North Water transfer Project through the Yellow River tunnel. The construction risk of the tunnel is evaluated by using AHP and grey cluster method, respectively, in the middle line of the South-to-North Water transfer Project. Based on the objective and effective risk assessment model, the risk grade and the overall risk grade of each level factor in the construction of the Yellow River tunnel in the middle route of the South-to-North Water transfer Project are analyzed.
