| Abstract: | A brief review is given for the present status as well as the existing problem in the study on the reliability and failure probability in the safety evaluation of the high arc dam with the analysis of the major failure mode.A fault tree model of the high arc dam system is established.The distribution regularities as well as the eigenvalue calculation method for the major random variables relevant to the high arc failure are investigated.An attempt is made to apply the JC method to the calculation of the failure probability with the single failure model of the high arc dam.The method for calculating the failure probability of the high arc dam system with multiple failure models is studied.The failure probability of a high arc dam is given. |
