Research on Standard of Acceptable Risk for High Arch Dam in Developing Countries


Article Preview

It is proposed to make use of dam risk rate, economic loss risk value and life loss risk value in evaluating the risk of high arch dam. The acceptable standards of risk for high arch dam in the developing country should not be set too high,it should reflect the level of economic and technology development, the policy for energy sources,the life value as well as the degree of the importance attached. Based on study of the characteristics of high arch dam and by means of the comparison of the levels of economic development, the life values and the degrees of the importance attached between developing and developed countries, as well as the analogy analysis of rare risk events occurring in developing countries, the reference value of the single high arch dam acceptable risk rate, economic loss risk and life loss risk in developing countries are found to be 10 /(yr dam) 6 ⋅ − , 10000$/(yr ⋅ dam) and 0.001person/(yr ⋅ dam) respectively;a method is worked out for determining the acceptable risk rate,the acceptable economic loss risk value and life loss risk value.
