In this study, we proposed a new-type of circular perforated caisson breakwater consisting of a bundle of latticed blocks that can be applied to a small port such as a fishing port, and numerically investigated the hydraulic characteristics of the breakwater. The numerical method used in this study ...

원형유공케이슨 방파제에 적용한 공법의 특징은 무엇인가? | 본 연구에서는 전술한 유공회파블록제의 기능성을 보다 향상시킨 것으로, 어항 등과 같은 소규모 항에서 항내정온도 및 낚시와 같은 레크리에이션과 친수할동 등에서 안전을 동시에 확보할 수 있으며, 더불어 우수한 경관을 유지할 수 있는 격자블록결속에 의한 신형식의 원형유공케이슨 방파제를 개발한다. 이 방파제의 형식은 전술한 유공회파블록제에서 현장타설 말뚝으로 블록과 블록을 결속하는 공법은 동일하지만 반사율을 보다 저감시키기 위하여 유공회파블록의 배후에 슬리트케이슨 방파제와 같이 유수실을 적용한 경우이다. 여기서, 블록과 블록을 결속하여 내파안정성을 도모하는 공법은 대규모 항만의 외곽 방파제에서 케이슨과 케이슨을 뒷채움재 혹은 케이블 등으로 결속하여 장대케이슨을 계획 · 확보하는 Park et al. | |
월파량의 증가, 감소하는 요인은 무엇인가? | (1) 월파량에 대해, 유수실 폭이 넓을수록 월파량이 감소하며, 입사파고가 클수록 또는 주기가 길수록 월파량은 증가한다. | |
TTP 표면에 부착되는 미끄러운 해조류로 인해 유발되는 사고는? | (2017)에 따르면 2014년 실족으로 인한 추락사고가 총 95건(이 중에 사망사고는 26명), 2015년에 실족으로 인한 추락사고가 총 100여건(이 중에 사망사고는 약 20%)이 발생하였다. 이러한 안전사고는 TTP 표면에 부착되는 미끄러운 해조류에 의한 실족사고와 반사율의 저감을 위해 TTP 사이에 형성된 공극으로의 추락사고, 경우에 따라서는 사망사고로도 이어지는 불상사가 빈번히 발생하고 있다. 그리고, 매년 반복되는 폭풍파랑의 내습으로 중력식 호안 및 중력식 방파제에 피복된 TTP의 안정중량 부족으로 인한 산란과 기초지반의 세굴 등으로 인한 TTP의 활동으로 전술한 안전문제는 보다 악화되고, 또한 경관상에 악영향을 주면서 친수공간으로의 이미지가 저하되어 사용자 측면에서 악영향을 초래한다. |
