Abstract
Construction process conversion of highway tunnel deep shaft is complex, little experience in design and construction, the construction process there is a big safety hazard. In the current there is no corresponding guideline and norm basis for domestic shaft construction risk assessment, and there are few researches on the safety risk assessment of highway tunnel shaft construction. Based on the investigation and analysis, this paper for a highway tunnel deep shaft engineering establishes risk assessment index systems and methods for the wellhead instability risk and the high-altitude fall risk of hoisting system, obtains the safety risk grade of the above two risks, and puts forward targeted risk control measures. These results provide a reference for similar risk assessment projects in the future.
