Study on System Reliability of Gravity Dam

Abstract:

Reliability analysis is an emerging field of structural engineering which is very significant in structures of great importance like arch dams, large concrete dams etc. The research objective is to design and construct a new method for the analysis of the system reliability of dam. The failure paths are searched out after failure mode and composite performance functions are set. Bayes formula and Cauchy-Schwarz Inequality are adopted to deduce the upper limit of failure probabilities in some failure modes that can obtain the failure probability of system of dam. A test example is given to verify this method. Compared with other conventional algorithm, this method has the strong points: more failure paths are considered and more safety methods are used to estimate the system reliability of dam.
