Soil name	Soil composition	Soil stage
Miscellaneous fill	Construction waste, household garbage, slag, residual soil	Moist and loose
Silty clay	Iron manganese nodules	Tawny, containing a few brown or black spots, moist, medium strength and toughness, good ductility
Medium sand	Mainly feldspar quartz sand, mixed with coarse gravel and a small amount of clay	Brown yellow, moist, medium density, uniform particles
Gravel	Mainly feldspar quartz sand, containing 3-7% pebbles, with good gradation and local coarse-grained lens	Brown yellow, saturated, dense, the maximum pebble diameter is 50 mm
Shingle	Mainly feldspar quartz sand, containing a very small amount of pebbles, mixed grain structure, inclusion of medium sand, and a small amount of clay	Brown yellow, saturated, dense
Pebble	It is composed of weathered crystal rock debris, and the filling material is mixed sand with good gradation, coarse sand and medium sand, and quick fertilizer layer	The maximum particle size is 80 mm, hard, saturated, and dense
