某国道321线改建公路工程路基施工技术研究

Research on Roadbed Construction Technology of a National Highway 321 Road Reconstruction Project

我国部分现有公路的现状已难以适应新时期的交通需求,对公路实施改建也成为各地改善交通水平的主要举措。本文以某国道321线改建公路工程为例,分析在改建工程中的路基施工技术。本文首先介绍了在该改建公路路基施工过程中的施工要点、旧路处理和技术路线,为后续路基施工技术的顺利开展奠定基础。而后通过在改建工程中实施路基开挖技术、路基填料及填筑技术、新旧路基搭接技术、路基防护与排水技术以及施工质量控制,该改建公路得到了如期和高质量竣工和验收通车,缓解了当地的交通拥堵。

This paper takes a national highway 321 road reconstruction project as an example to analyze the roadbed construction technology in the reconstruction project. This paper first introduces the construction key points,old road treatment and technical route in the process of roadbed construction of the rebuilt highway, laying a foundation for the smooth development of roadbed construction technology. After that, through the implementation of roadbed excavation technology, roadbed filling and filling technology, new and old roadbed overlapping technology,roadbed protection and drainage technology and construction quality control in the reconstruction project, the reconstruction highway was completed on schedule and with high quality, accepted and opened to traffic, and alleviated the local traffic congestion.
