Geologic parameters of structural planes in the dam site.

Classification		Strength against shear fracture
Category	Subcategory		/MPa
Hard structural plane		0.60~0.70	0.10~0.15
Weak structural plane or fault-fractured zones	Clastic and fragment	0.45~0.50	0.10~0.15
	Clastic with mud	0.35~0.40	0.05~0.10
	Mud with silty grain clastic	0.25~0.30	0.01~0.05
	Clayey mud	0.18~0.25	0.002~0.010
