A Risk Assessment Model for Dam Combining the Probabilistic and the Nonprobabilistic Methods

Table 1

Target reliability index and of dam.

Structure safety grade			I grade	II grade	III grade
Damage type	The first kind of failure	Probability target	3.7	3.2	2.7
	The second kind of failure	Reliability index	4.2	3.7	3.2
	The first kind of failure	Nonprobability	1.3	1.2	1.1
	The second kind of failure	Target reliability index	1.4	1.3	1.2
