Quantitative model of time-efficient indexes for evaluation of reinforcement effect of dam

The basic indexes for evaluation of a dam's reinforcement effect include time-efficient indexes and non-time-efficient indexes. The quantification of time-efficient indexes is the key to quantitative evaluation of the reinforcement effect of a dam. Since there is a lack of theory on quantification of time-efficient indexes in the reinforcement evaluation system of dams, in this paper we studied the influence of the change of dam behavior and the change of index level on the evaluation of time-efficient indexes, deduced the formulas for safety degree and grade promotion coefficient on the basis of the dimensionless quantitative time-efficient indexes, and then established a quantitative model of time-efficient indexes. The reinforcement of a reservoir in Jiangxi was taken as an example. We analyzed the changes of the time-efficient evaluation indexes before and after reinforcement, and verified the rationality of the model. The results indicated that the time-efficient indexes can be reasonably evaluated by the proposed quantitative model of time-efficient indexes.
