- Abstract:
- Liquid limit and plastic limit of soil reflect soil infiltration, erosion, corrosion and shear, etc, which has the important significance on the research of soil erosion of Benggang. In this study, liquid limit and plastic limit, soil particles and soil organic matter in red soil layer were surveyed and evaluated in order to analyze the influences of soil organic matter content and soil particle size distribution on the soil liquid limit and plastic limit. The results showed that the soil in red soil layer of Benggang is the clay soil with high liquid limit, soil status is hard; liquid limit and plastic limit did not have an obvious correlation with coarse, fine sand and silt contents, and they showed a binomial relationship with extreme fine sand. Among them, extreme fine sand content was negative correlation with liquid limit and plastic limit; clay content was significant positive correlation with liquid limit and plastic limit. The simulation equation can accurately describe the relationship between liquid limit and plastic limit and various factors. These study findings will enrich the research of erosion mechanism of Benggang.
