Grade classification of influencing factors of preliminary design.

Assessment grade	Wet density (kg·m^−3)	Compressive strength (MPa)	Filling aspect ratio	Safety factor	Slope rate of connecting surface (°)	Steel wire mesh setting
Excellent	[500, 1000)	[3.5, ∞)	(0, 1)	[1.5, ∞)	(0, 45]	Excellent
Good	[1000, 1500)	[2, 3.5)	[1, 1.5)	[1.3, 1.5)	(45, 90]	Good
General	[1500, 2000)	[0.5, 2)	[1.5, 2)	[1.2, 1.3)	(90, 135]	General
Poor	[2000, ∞)	[0, 0.5)	[2, ∞)	(0, 1.2)	(135, 180]	Poor
