根据国家科技支撑计划“高海拔高寒地区高速公路建设技术”的研究内容,为解决多年冻土区因路基变宽而引起的一系列问题,必须依托现有的工程进行相应的试验示范,以优化处治方案,总结提炼适合青藏高原高速公路的合理技术与建设方案。根据该项目需要及高原多年冻土区现有工程进展情况,选取拟建的共和至玉树(结古)公路改扩建工程及花石峡至大武公路扩建工程作为依托工程,遴选适当路段布设试验工程,进行相关试验示范研究。
According to the national science and technology support plan and the research content of highway construction technology in high altitude and alpine region, in order to solve a series of problems caused by the widening of roadbed in permafrost regions, we must rely on the existing projects to carry out corresponding experiments and demonstrations, To optimize the treatment plan, summarize and refine the reasonable technology and construction scheme suitable for the expressway in the Qinghai-Tibet Plateau. According to the needs of the project and the progress of the existing projects in the permafrost region, the proposed reconstruction and extension project of the Republican-Yushu (Jiegu) Highway and the expansion of Huashixia to Dawu Highway are selected as the relying projects, Relevant pilot demonstration study.
