影响高原地区路基施工质量因素及提高措施

The factors affecling subgrade construction quality in plateau area and improving measures

高原地区由于地形、气候等多方面的影响,长期存在的冻土会对公路路基施工产生重要影响,如何提高高原地区的路基施工质量,减少冻土等对公路路基质量的影响,是高原地区路基施工必须解决的一个问题。文章以四川G318巴塘-芒康路段施工为例,阐述了影响高原地区路基施工质量的因素,并提出改进措施,希望能对相似路段的设计施工提供借鉴。

Plateau area because of the influence of the terrain, climate, perennial frozen soil can have an important impact on highway subgrade construction, how to improve the quality of subgrade construction of plateau area, reduce the impact of fro- zen soil on the quality of highway subgrade is a problem must be solved in plateau area. Takes Batang- Mangkang, G318, Si- chuan section as an example, this paper expounds the factors affecting the quality of subgrade construction in plateau area, and puts forward improvement measures, hoping to provide reference for the design and construction of similar sections.
