Research on the Green Construction Evaluation System for Urban Underground Utility Tunnels

To address issues such as the numerous factors and unreasonable weight allocation in existing green construction evaluation systems for urban underground utility tunnels, this paper systematically reviews relevant domestic and international research and, considering the unique characteristics of underground utility tunnels, proposes evaluation factors encompassing four dimensions: resource utilization, environmental impact, construction management, and technological innovation.Through the Delphi method, the evaluation factors were screened and refined, ultimately leading to the identification of six core indicators: application of trenchless construction techniques, recycling and utilization of spoil, innovation in green construction techniques, application of information technology, conservation of energy and material resources, and integrated control of dust and noise pollution.These core indicators collectively embody the intensive nature, circularity, technological innovation, and environmental sensitivity inherent in the green construction of utility tunnels. Validation results using the fuzzy comprehensive evaluation method demonstrate that the proposed system can effectively assess the green construction performance of different construction methods. This study provides a scientific basis for standardizing and promoting the sustainable development of green construction practices for urban underground utility tunnels, thereby advancing the green transformation of urban infrastructure development.
