摘要
采用干土法和湿土法对桂林红黏土特性进行了击实试验研究,从桂林红黏土失水程度对结合水膜的影响探讨了不同备样方法对桂林红黏土最优含水率及最大干密度的影响,并分析了导致不同试验结果的原因。结果表明:桂林红黏土凝胶胶结结构中双电层失水多少与土样制备方法有关,不同备样方法对桂林红黏土的最优含水率及最大干密度影响显著。该研究可为红黏土工程实践和土工试验提供理论依据。
This paper adopts water reducing method and wetting method to make compaction tests for ana- lyzing the characteristics of Guilin red clay. Based on the impact of the water loss degree of Guilin red clay on combined water film, the paper discusses the impact of different preparation methods on the optimum moisture content and maximum dry density of Guilin red clay and analyzes the causes leading to different results. The results show that the dehydration degree of electric double layers in the gel cementing struc- ture of Guiling red clay is related to the preparation methods, and different preparation methods have obvi- ous impact on the optimum moisture content and maximum dry density of Guilin red clay. The study pro- vides a theoretical basis for the engineering practice and geotechnical tests of Guilin red clay.
