Abstract
Widely-graded soil deposits are very common in nature, including colluvial soil landslides, residual soil slopes, the natural loose-packing dams of barrier lakes, glacial till deposits, etc. For example, quite a number of the natural slopes in the Three-Gorges Reservoir Zone (TGTZ), landslides in Hong Kong, and colluvial soil deposits formed after the Wenchuan earthquake are composed of colluvial soils. The grain-size analysis of colluvial soils reveals that such soils are often widely-graded with a small sand fraction and show a bimodal feature of grain-size distribution.
