Economical Risk Analysis on Design Safety for Seepage Prevention System
Economical risk analysis is widely used in engineering projects, and has much influence on the optimal decision method. It is of vital importance to find out the optimal seepage controlling scheme to meet with the unification of safety and economy. For this purpose, it is desirable to develop a practical decision making method which can accurately predict the risks of dam failure and can estimate the total expense of seepage prevention system. This paper deals with a new method for determination safety and design standard of seepage prevention system. The safety of dam is expressed by the necessity of leakage treatment. Based on the economical investment principle, a risk decision model was submitted to optimize design on seepage prevention. The method indicates the unification of safety and economy for seepage prevention system. An application of the method on seepage controlling of copper tailings-dam shows its feasibility and rationality.
