Abstract

The risk assessment model for hydrlolgic safety analysis of dam and levee in developed by using Monte-Carlo and AFOSM (Advanced First-Order Second-Moment) method. The fault tree analysis and four phases approach are presented for the safety eveluation of risk of dam and levee. The risk model consists of rainfall-runoff analysis, reservoir routing and channel routing considering the variations in the model parameter. For the rainfall-runoff analysis, KRRL method is adopted with 200-year precipitation and PMP (Probable Maximum Precipitation). Reservoir routing is performed by fourth order Runge-Kutta method and channel routing by standard step method. The suggested model will contribute to safety evaluation of dam and levee and their rehabilitation decision problem.

본 연구는 댐 및 하천제방에 대한 수문학적 위험도 평가를 위해서 Monte-carlo 기법과 AFOSM 기법에 의한 위험도 모형을 개발하였다. 댐 및 제방에 대한 위험도 해석을 위하여 fault tree를 작성하였고, 단계별 위험도 평가과정을 제시하였다. 본 연구의 위험도 모형은 모형 매개변수에 대한 변동성을 고려하여 강우-유출해석, 저수지 추적, 하도추적 등으로 구성하였다. 강우-유출해석에 있어서는 200년 빈도 및 PMP에 의한 설계강우에 대한 KRRL법에 적용되었다. 저수지 홍수추적은 4차 Runge-Kutta법을 이용하였고, 하도부 추적은 표준축차계산법에 의한 부등류 해석을 실시하였다. 본 연구 모형은 기존의 댐 및 제방에 대해서 홍수시 안전도 평가와 유지보수의 정책결정 등에 기여할 수 있는 모형으로 제시하였다.
