Research on Management Models and Key Technologies of Urban Integrated Utility Tunnels

Abstract

As a typical urban lifeline infrastructure, integrated utility tunnels play a crucial role in enhancing urban operational safety, optimizing spatial environments, and improving carrying capacity. This paper systematically reviews domestic and international management models of integrated utility tunnel construction, compares their advantages, disadvantages, and applicable conditions, and analyzes the key factors influencing model selection. On the technical side, construction methods, performance design, and the application of information technologies such as BIM and GIS are investigated. In response to challenges including incomplete policies and regulations, high construction and operation costs, and complex system management, optimization strategies are proposed: in terms of management, the promotion of PPP models, corporatized operation, and property-based management with a paid-use system; in terms of technology, strengthening intelligent monitoring and early warning, BIM integration, and pipeline information platforms; in terms of policy, improving the regulatory framework, reinforcing technical standards, and enhancing public awareness to create a favorable environment for tunnel construction and operation.
