Effects of Earthquake on Behavior Characteristics of Fault Gouge in Time-History Analysis of Slope

Table 2

Applied physical and mechanical properties for the time-history analysis of each rock type. The slope consists of soil and fault gouge that originated from granite and sedimentary rock, and slightly weathered (S.W.), moderately weathered (M.W.), and highly weathered (H.W.) sedimentary rocks.

Rock type Soil		Unit weight (kN/m³)	Cohesion (kPa)	Friction angle (°)	Dynamic elastic modulus (MPa)	Dynamic Poisson's ratio
		18.8	7	35.5	917	0.444
Granite	Fault gouge	18.0	15	27.8	1,073	0.269
Sedimentary rock	S.W.	26.0	10,830	55.4	27,400	0.322
	M.W.	24.6	11,250	53.0	18,618	0.336
	H.W.	21.0	9,000	54.5	1,650	0.471
	Fault gouge	19.6	11	27.7	1,452	0.269
