Systematically analysing the method on the failure approach of patten recognition of the flood control hydro-project system, combining the social economical efficiency of the flood control system"s invalidation losses, the paper provides the concept "flood disaster risk " and constitutes the failure analysis approach of patten recognition system on the base of the flood progress. Combining with the subsystem functions and the failure probabilistic analysis of the hydro structure, the paper discusses the main failure approach of patten recognition and calculus of failure probability, calculates flood control hydro-project"s total risk.
