As the number of aging dams is increasing, an efficient and feasible probabilistic method is required to analyze the uncertainties of a dam system with multiple failure modes. Due to the limitation of huge computation of Direct Simulation Monte Carlo, a new method is introduced to solve the reliability problem of a dam system. This new method determines the failure domain of a complex structure by resorting to lines rather than random points. It is used to calculate the failure probability and reliability sensitivity of a gravity dam, which is a large, complex structure with small probability; and the basic Monte Carlo method is also used for comparison. Results show that the new method is more efficient and feasible to analyze the reliability of a dam system with small failure probability and multiple dimensionalities.
