浅谈高寒山区脆弱生态无植被边坡防护施工工艺

Discussion of Construction Technology of Fragile Ecology Non-Vegetated Slope Protection in Alpine Mountainous Areas

在国道高海拔地区路段进行干线公路改造施工,不能仅按照低平原地区传统施工作业方式而进行,还需考虑应用稀土高海拔地区的施工气候条件及相符合国家标准的一系列全新公路技术方案措施与路面养护工艺措施,并进行实践研究探索与综合应用,从而确保公路质量。本文以甘肃S232项目载体为研究实例,对高海拔路基边坡防护工艺进行实践分析,切实解决高原冻土公路路基边坡防护施工难点,同时也为同行业提供一定有价值的参考。

The renovation construction of trunk highways of national trunk highway in high-altitude areas should not be carried out in accordance with the traditional construction operation methods in low-plain areas,and also needs to consider the construction climatic conditions in rare earth high-altitude areas and a series of new highway technical scheme measures and pavement maintenance measures in line with national standards,and carry out practical research and comprehensive application,so as to ensure the quality of highways.This paper takes the Gansu S232 project carrier as a research example to conduct a practical analysis of the high-altitude subgrade slope protection process,effectively solve the difficulties of subgrade slope protection construction of plateau permafrost highway,and also provide a valuable reference for the same industry.
