戈壁地区公路路基工程施工管理与质量控制

Construction Management and Quality Control of Highway Subgrade Engineering in Gobi Desert Area

路基是在天然地表面通过堆填或开挖而成的具有纵向线形和横向断面的土石结构物。在道路工程中,路基工程是基础部分,也是主要组成部分。戈壁地区道路沿线地形起伏,地质地貌和气象特征比较恶劣,且道路沿线基本无社会依托,导致路基工程施工复杂困难、特殊性强。结合实际工程,从施工部署管理、质量控制、制度措施等方面阐述了戈壁地区路基施工管理与质量控制的具体方法,总结经验和问题,为戈壁地区路基工程施工提供一定参考。

Subgrade is a kind of earth rock structure with longitudinal alignment and transverse section formed by filling or excavation on natural ground surface.In the road engineering,the subgrade engineering is the foundation part,also is the main component.In Gobi area,the terrain along the road is undulating,the geological landform and meteorological characteristics are relatively bad,and there is basically no social support along the road,which leads to the complexity,difficulty and particularity of subgrade construction.In this paper,combined with the actual project,from the construction deployment management,quality control,system measures and other aspects,elaborated the specific methods of subgrade construction management and quality control in Gobi area,summarized the experience and problems,and provided certain reference for the construction of Subgrade Engineering in Gobi area.
