摘要
通过对砂性土击实试验数据的归一化处理并与粘性土的对比,研究分析砂性土中粒径小于0.075mm的细粒含量对砂性土Proctor曲线线形的影响,总结提出砂性土的压实机理,同时分析颗粒级配、压实类型等对砂性土压实性的影响及解决办法。
Through the normalization treatment of the compaction test data of sandy soil and compared with clayey soiL, this article performs a study and analysis of thc impacts of the sandy soil less than 0.075mm in grain size on the proctor curve. Summarizing and putting forward the compaction mechanism of sandy soil, it simultaneously makes an analysis of the impacts of grain size gradation and type of compaction on the compactness of the sandy soil and the solution thereto.
