基于熵权-正态云模型的小净距隧道施工风险评估模型
Risk assessment model of small clear distance tunnel construction based on entropy weight and normal cloud model
摘要
Abstract
With the development of infrastructure construction in our country,more and more small clear distance tunnels have been constructed in the highway.Meanwhile,due to the geological conditions,some small clear distance tunnels may pass through the loose deposits,and there are many risk factors that affect the construction safety,with fuzzy and complex relationships and high ancertainly in risk factors resulting in various uncertainties in the probability of risk occurrence.For small clear distance tunnels through rock piles,a risk assessment model based on entropy weight-normal cloud model was proposed for the construc-tion of small clear distance tunnels.Fifteen evaluation indexes from four aspects,including engineering geo-logical conditions,tunnel design,external factors and engineering control,are selected.Taking an actual tunnel project as an example,the feasibility and unique advantages of the application of the model in the quantitative assessment of the construction risk of small clear distance tunnels are demonstrated,which is of some reference significance for the construction risk assessment of other similar projects.关键词
