刚果(布)砂壤土填方路基施工质量控制

Construction Quality Control of Sandy Loam Fill Subgrade of the Republic of Congo

砂壤土是在公路填方路基施工中常见的土壤类型,在非洲大陆就更为常见。以刚果(布)英布鲁水电枢纽进场公路工程为背景,分析了影响非洲砂壤土填方路基工程质量的因素,并对诸如基底施工、现场试验以及路基碾压等施工质量控制的关键环节分别进行了阐述,最后对如何保证砂壤土路基施工质量提出了建议。

Sandy loam is a common soil type in highway fill subgrade construction,which is more common in African continent.Taking Imboulou hydroelectric power approach highway engineering of the Republic of Congo as the background,factors of influencing African sandy loam fill subgrade engineering quality are analyzed,key points on quality control of construction like basement construction,field test and rolling compaction of subgrade and so on are elaborated,and suggestions of how to guarantee the sandy loam subgrade construction quality are put forward finally.
