Application of Improved Questionnaire in Recognizing of Risk Sources in Subway Station Construction with Open-Cut Method

摘要

There are many uncertainty risks during the construction of tunnels and underground works, which are both significant and numerous. Risk analysis and assessment is fundamental for risk management in tunnel and underground engineering. In this paper, by analyzing the characteristics of subway station construction with open-cut method, accidents that have occurred, and extensive collection of relevant information, a more comprehensive risk sources in subway station construction with open-cut method are listed. Further more, improved questionnaire has been applied in construction site research, which shown that subjective information has been extracted accurately and accepted by a lot of people.
