Abstract

With the rapid development of urban rail transit, the issue of level crossings between train access lines and ground roads has become increasingly prominent, leading to frequent occurrences of “dead-end roads” that severely impact citizens’ travel experiences and urban traffic efficiency. To address this problem, this paper takes an underpass project in a railway switch area as an example, employing the Unified Bored Immersed Tube (UBIT) method for underpass construction and using the Fuzzy Comprehensive Evaluation (FCE) method to assess risks throughout the project. By establishing a hierarchical structure of risk factors and a quantitative index system, this paper identifies four major categories of risk factors: construction conditions, design plans, construction plans, and operational management. The Analytic Hierarchy Process (AHP) is used to determine the weights of each factor. The research results indicate that structural design and construction process control factors have the greatest impact on risk control, with a comprehensive risk assessment value of 4.26, classified as medium risk, necessitating corresponding control measures and emergency plans. This study provides a systematic risk assessment method and reference for similar projects.
