[Abstract]:People pay more and more attention to the safety construction and safety management of highway tunnel. How to evaluate and control the various risks in the process of highway tunnel construction in order to ensure the safe, economical and efficient implementation of highway tunnel construction. It has become an urgent problem to be solved in the field of theory and engineering. It is of great social significance to study the evaluation and management of highway tunnel construction safety risk and make reliable prediction and evaluation of construction safety risk. On the basis of consulting relevant documents extensively, this paper summarizes the present research situation of tunnel construction safety management at home and abroad, taking highway tunnel construction safety risk as research object, combining risk management theory and engineering example. In order to support the stability of surrounding rock and the adjustment of supporting parameters, the stress and deformation characteristics of tunnel excavation are simulated by 3D software. Combined with the construction scheme, the expert investigation method is used to identify the risk sources that affect the safety of the tunnel construction, and the risk evaluation index system is constructed according to the typical risks. By using the analytic hierarchy process (AHP) and fuzzy comprehensive evaluation method, the safety risk grade of tunnel construction is determined, and the influence degree of risk factors on tunnel construction safety risk is grasped intuitively. Based on the construction organization structure and system, the paper explores the safety management system and risk management measures of highway tunnel construction, and realizes the effective control of the tunnel construction safety risk. Combined with practical examples, the advanced geological forecast and engineering site safety monitoring system are designed. Through the analysis of the measured data of the project and the theoretical analysis, the tunnel construction safety risk control is realized, and the good results are obtained. It has reference significance for similar projects and provides reference for fine and safe construction of highway tunnel.
