Abstract: Aiming at the problem of soil particle dispersion in grain distribution analysis densimeter test, the orthogonal test design method was used to analyze the influence of soaking, boiling and dispersant on soil particle dispersion, and the optimal scheme was determined. According to the analysis results and the actual project, the feasibility of the scheme is verified by comparison, and the efficiency of grain distribution analysis densimeter test is improved, time cost is saved.

Key words: orthogonal test design, densimeter method, soaking, boiling, dispersant
