Safety Standard for Special Class Damslopes Based on Reliability Analysis

Table 8

Proposed value of risk control standards for stability of special dam and slope.

Building type	Class	Yearly failure probability	Reliability index
Earth-rockfill dam	Special class 1	10^–8	4.70
	Special class 2	5 × 10^−8	4.45
	Class 1	10^–7	4.20
Slope	Special class I	10^–7	4.20
	Special class II	5 × 10^−7	3.95
	Class I	10^–6	3.70
