Abstract
This article takes the safety risks of highway tunnel construction as the research object,and introduces the K-means clustering algo-rithm into the risk assessment process.By identifying the risks of highway tunnel construction,a safety risk assessment system for highway tun-nel construction covering 22 indicators has been established from four aspects:geology,design,environment,and construction factors.Taking the safety risk assessment of a highway tunnel construction project in Chongqing as an example,the LEC method will be combined with K-means clustering algorithm to classify safety risk levels.According to the risk calculation results,the construction safety risk of this project is level Ⅱ,and the possibility of safety risk occurrence is high,which should be taken seriously.关键词
