Theoretical and Case Studies of Interval Nonprobabilistic Reliability for Tailing Dam Stability
Table 5
The advantages and disadvantages of the safety factor, the random reliability, and the nonprobabilistic reliability.
| Methods | The considered parameters | Advantages | Disadvantages |
| Safety factor | The mean values of the mechanical parameters. | Easy to operate. | The uncertainty of the parameters is not considered. | Random reliability | The mean values and the probability density functions of the mechanical parameters. | The uncertainty of the parameters are considered; the reliability index and the probability of failure can be obtained. | Large amounts of data are needed to get the probability density functions, which consume much more manpower and material resources. | Interval nonprobabilistic reliability | The interval values of the mechanical parameters. | The interval values of the parameters are easy to get without the need of probability density functions; the reliability index can be obtained. | ā |
