摘要: 贵州盘县某项目挖、填方工程地基采用强夯进行处理,现场采用灌水法进行压实度检测,最大干密度的确定采用室内击实试验及现场试验两种方法,通过试验成果的对比,表明室内击实试验剔除了大于40 mm以上粒径的碎石土,与现场实际粒径不相符,应采用现场试验确定碎石土最大干密度。

Abstract: The site for the Coking Coal-Electricity-Steel integration project in Panxian County, Guizhou, is required to have high cut and high fills. The fill area is improved by the dynamic compaction and the degree of compaction after the compaction should be greater than 97% of the maximum dry density. The water-fill method is used for the in situ density test. Comparing with the laboratory Proctor test results, it is found that the in situ testing is more realistic since soils with grain size larger than 40 mm are removed in the Proctor test.
