公路工程“无废工地”实践路径研究

Research on the Practical Pathways for “Zero-Waste Construction Sites” in Highway Engineering

摘要: 随着公路工程建设规模的持续发展，其产生的固体废弃物污染问题日益突出，已成为制约行业可持续发展的关键因素之一。文章以G1503公路和周邓快速路浦东枢纽段工程为研究对象，系统探讨了“无废工地”理念在桥隧结合线性工程中的实践路径。通过项目立项阶段的全过程指标筹划、设计阶段的源头减量优化、施工过程的预制装配与循环利用技术，以及废弃物的精细化分类与资源化处置，构建了完整的“无废工地”管理体系，项目实现了显著的资源节约与环境效益，为同类工程提供了可复制、可推广的“无废工地”建设范式，对推动交通基础设施建设绿色低碳转型具有重要参考价值。

Abstract: With the continuous development of highway engineering construction, the pollution caused by solid waste is becoming increasingly prominent and has become one of the critical factors constraining the sustainable development of the industry. This paper takes the G1503 highway and the Pudong Hub Section of the Zhou-Deng Expressway project as the research objects to systematically explore the implementation pathways of the “Zero-Waste Construction Sites” concept in linear projects involving bridges and tunnels. Through the full-process index planning in the project initiation stage, the source reduction optimization in the design phase, the prefabrication and recycling technologies during construction, the refined classification and resource-based disposal of waste, a comprehensive “Zero-Waste Construction Site” management system was established. The project has achieved remarkable resource conservation and environmental benefits. This research provides a replicable and scalable “Zero-Waste Construction Sites” model for similar projects, which has significant reference value for promoting the green and low-carbon transformation of transportation infrastructure construction.
