碩士 / 國立中興大學 / 水土保持學系所 / 94 / This study is the seepage estimate of Liyutan earth dam, seepage volume is the only one direct and sweeping reflects the earth dam condition on all over the dam monitoring. And it is the indication of the dam safety assessment. The actually seepage volume be affected by the reservoir elevation and precipitation, but dam safety is no relation with the seepage be affected by precipitation.
The study use the new way to improve the seepage monitoring devices during initial rising of reservoir water elevation（1996/9-2006/4）,let the device avoid the caco3 in water and time/container method become automatic measuring system.
To sieve the seepage data that haven’t be affected by precipitation and reservoir water elevation to seepage volume’s r(correlation Coefficient,)>0.85 from dry season, to establish all possible regression Analysis from data have been sieved, and select the best regression curve from them. The regression curve not only can estimate the seepage with reservoir water elevation but can become original condition index curve of dam.
To establish the condition index curve regular, it can assess dam condition with different time, according to the result of condition index curve. The method is feasible and been proved by seepage data of before and after 921 earthquake. People can use this method to maintain and sustainable management reservoir.
Keywords: liyutan, earth dam, seepage, correlation coefficient, regression analysis, condition index curve
