dc.description.abstract 항만 리모델링을 위한 콘크리트 시설물에 대한 평가가 필요하며, 특히 리모델링이 결정된 경우에는 소파 블럭이나 케이슨 블록 등에 대한 재활용 여부를 평가하여 재활용이 가능할 경우에는 유용하는 것이 경제적인 리모델링에 도움이 될 수 있다. 이 연구에서는 콘크리트 항만시설물에 대한 건전성 평가 및 재활용성 평가를 위하여 기존의 초음파 속도법을 비롯하여 슈미트 해머를 이용한 반발경도법, 충격반향법, 표면파 속도법 등의 비파괴시험을 실시하였다. 국내 5개 항만에 대하여 비파괴시험 및 시편을 채취하였으며, 채취한 시편에 대한 압축강도 시험을 수행하여 비파괴시험 결과와 비교하였다. 비파괴시험결과와 압축강도 시험을 통하여 콘크리트 재료의 탄성계수와 압축강도 등을 평가하였다. Recently harbor remodeling projects are seriously considered to enhance the loading and unloading capability of old container terminals and to make decrepit ports as eco-friendly harbor and waterfront spaces in many countries. In such a case, quantitative and qualitative evaluations on concrete harbor facilities are mandatory to determine the current structural integrity condition of aged materials. Once the remodeling project is determined to be carried out, the reusability of individual structural members and facilities including caissons, cell-blocks, and tetra-pods need to be decided based on the simple and economic visual inspection and/or nondestructive testing. In this study, the systematic quantitative evaluation procedure for determining the structural integrity condition and the reusability is studied based the nondestructive testing and evaluation methods. Conventional methods including Schmidt hammer test and ultrasonicpulse velocity methods and elastic wave based methods including impact echo test and surface wave test are applied to the old harbor facilities in five different sites. The compressive tests are also carried out to determine the elastic modulus and compressive strength of concrete materials. -
