Abstract

This paper uses similar theory to configure a kind of expansive soil to carry out indoor model experiments. By selecting sand, gypsum, and bentonite to artificially configure a mixture with similar expansion and contraction characteristics, the expansion characteristics of expansive soil are studied under water immersion conditions. The experimental results show that the mixture is mainly divided into three changing processes after adding water, the rapid expansion stage, the low-speed expansion stage, and the stable stage. With the changes of bentonite content, gypsum content and sand content, the mixture exhibits different expansion rates, which provides a certain theoretical reference for similar materials in geological model experiments.
