교각에서 국부세굴을 일으키는 근본적 원인은 하상에서의 와류의 형성인 바, 교각주위에서 발생하는 와류중에서 교각전면에서 발생하여 하강류(downflow)에 의해 발생되는 와류를 말굽형와류 (horseshoe vortex)라 하고, 교각 직하류에서 발생되는 와류를 후류형와류(wake vortex)라 한다. 세굴은 기초부로 유입되는 퇴사량보 다 제거량이 큰 경우 발생하게 되며, 시간이 지남에 따라 점차 세굴공( scour hole)과 교각 전면의 세굴심이 증가하게 되어 교각을 파손시킬 뿐만 아니라 하상토와 교각과의 마찰력이 떨어지면서 다리붕괴의 원인이 되고 있다. 이 와류계의 구조는 세가지 기본계인 말굽형 와류(horseshoe vortex) 및 후류형와류(wake vortek) 그리고 트레일링 와류(trailing vortex) 현상으로 구분되며, 이들 와류계의 현상이 전부 혹은 한 두가지 현상으로 구성된다.The primary cause of local scour in bridge piers is the formation of vortices in the riverbed.The vortices occurring around the pier among the vortices around the piers are called horseshoe vortex. For example, the vortex that occurs immediately downstream of a bridge is called a wake vortex. Scour occurs when the removal amount is larger than the amount of sediment flowing into the foundation, and as time passes, scour holes and scour depths in front of the pier gradually increase, which not only breaks the pier, The friction is falling, causing the collapse of the leg. The structure of this vortex system is divided into three basic systems: horseshoe vortex, wake vortek, and trailing vortex, which are all or one or two phenomena. do.
