Frequent unstable natural disasters worldwide in recent year caused damage to large power plants, high-rise buildings, dams and public facilities, resulting in a growing sense of anxiety among people. This is result in the increase of concern for the safety of residential as well as public infrastructure. Considering this growing concern for the public infrastructure a systematic safety evaluation is require. Thus, in this paper, the fragility of weir structure by considering the scour effect of flood was the focused of study. The weir structure in this study was located in Daegu city; it served as the power and water supply and flood prevention. The study was performed by conducting penetration analysis on the variables of the adjacent ground.
Based on the study of chloride migration coefficient and hydration heat evolution, it was found that the use of ternary blended cement was effective to achieve desired service life and minimum crack index. On the other hand, a high level of compressive strength is required for marine concrete mix design.
침투 해석 수치모형은 제방 침투와 관련된 문제 해석과 방지기법 설계에 있어 매우 유용한 방법이나, 각각의 수치 모형은 적용상 한계와 문제점을 내포하고 있다. 일반적으로 사용되고 있는 상용 프로그램은 적용하는 다양한 문제에 대해서 검증이나 보정이 이루어지지 않을 뿐 아니라, 사용자가 침투현상에 대한 정확한 지식이나 교육 없이도 결과를 도출할 수 있게 되어 있다. 본 연구에서는 해석해와 실험을 통해 침투 수치모형의 적합성과 적용 시 고려사항을 사용자적 입장
