Factors of safety for the foundation.

Item	Strength parameters		Factors of safety	Mean value of factors of safety	Standard deviation of factors of safety	Reliability index	Design point values
	Cohesion (kPa)	Internal friction angle (°)					Cohesion (kPa)	Internal friction angle (°)
Symbol	or	or
BSFM	16.63	24.18	2.3	3.15	0.58	3.69	15.974	0.297
SSFM	12.23	17.76	1.35	1.50	0.14	3.69	15.974	0.297

Note. The subscript denotes the parameters after strength reduction of the safety factor (corresponding to SSFM).
