Abstract
This study focuses on the challenges associated with the immersion of tunnel segments and underwater connection in undersea immersed tube tunnels,which require high precision but are susceptible to difficulties due to complex marine,geological,and environmental conditions.These conditions may negatively impact the measurement work and ultimately lead to quality issues in the project.The paper first conducted a risk evaluation of the measurement process for immersed tube tunnels based on risk evaluation theory.The analytic hierarchy process(AHP)method and fuzzy comprehensive evaluation method were integrated to evaluate measurement risks,identify the risk factors at each level,and process the evaluation indi-cators.A risk evaluation matrix was then used to determine the primary measurement risk factors and the risk level of the immersed tube tunnel measurement.Finally,a risk evaluation of the measurement work for the immersed tube tunnel in the Hong Kong-Zhuhai-Macau Bridge was presented as a case study.Based on the identified risks,probabilities,and potential losses,appropriate preventive measures were implemented to mitigate risks and ensure the smooth progress of the measure-ment work.关键词
