摘要
针对广西北部湾沿海地区的低液限粉土的颗粒组成问题,以土样结构性差异作为切入点,采用移液管法对不同状态的土样进行颗粒组成分析试验。试验结果显示土的结构性差异对土的颗粒组成分布有着重要影响。对土颗粒组成的新认识,为后续探讨该地区低液限粉土颗粒变异性以及确切的命名、工程性质评价提供了重要依据,在沿海公路路基修筑方面有重要的指导价值。
Aiming at the problem of particle composition of low liquid limit silt in Guangxi Beibu Gulf Coastal area,the method of liquid-transfer tube was used to analyze the particle composition of soil samples in different states. The results show that the structural difference of soil has an important influence on the distribution of particle composition. The new understanding of the composition of soil particles provide an important basis for the further study of the particle variability of low liquid limit silt in this area and the evaluation of the exact nomenclature and engineering properties,which has important guiding value in the construction of coastal highway subgrade.
