To study the effect of sand content on the rheological properties of lacustrine soft soil in northern Hunan, one-dimensional rheological consolidation tests under single-stage load were carried out with soft soil samples prepared with different sand content in the laboratory. The results show that the sand content has a significant effect on consolidation deformation of lacustrine soft soil in northern Hunan. The time of primary consolidation is almost unaffected by consolidation pressure, and decreases linearly with the sand/soil ratio. The higher the sand content in soil, the greater the consolidation pressure, and the smaller the secondary consolidation coefficient. The relationship between the secondary consolidation coefficient and the sand/soil ratio can be well represented by a power function. The higher the content of coarse particles in soft soil, the greater the fractal dimension. There is a linear relationship between the secondary consolidation coefficient and the fractal dimension.
