Abstract

Numerous water gates have been constructed and are under construction for the control of water level because, due to the topographical characteristics of mountainous area, many small size rivers are developed in Korean peninsula. Among the water gates, movable water gates are more efficient to control water level than the fixed water gates. By the field application of the movable water gates, many problems associated with the fixed water gates have been mitigated. The problems include the bottom water pollution, the change of habitats for the riparian organisms, etc. This is the reason to increase the field application of movable water gates. In the paper we present the result of analytical investigation pertaining to the structural behavior of multistage overturning movable water gate which is one of the movable water gates. In the analytical investigations, the finite element analysis on the constructed water gate has been conducted for illustration purposes and it was found that the multistage movable water gate is much better than the fixed and/or existing movable water gates in the point of structural and environmental performances.

우리나라의 지형 특성상 많은 중소하천들이 생성되어 있으며, 이에 대한 치수 목적으로 다양한 보가 건설되고 있다. 그 중 가동보는 고정보에 비해 저수위를 자유롭게 조절할 수 있고, 상류부 저층수의 수질악화, 수변 생물 서식처의 변화 등 고정보의 문제점을 개선할 수 있기 때문에 그 적용빈도가 증가하고 있는 추세이다. 이 연구에서는 가동보의 종류 중 하나인 다단전도방식 가동보에 대한 특징을 조사하고, 시공된 구조물을 예로 구조적 성능을 확인하기 위한 해석적 연구를 수행하였다. 또한, 유한요소해석을 통해 얻은 결과로부터 다단전도방식 가동보의 우수한 구조적 성능을 확인할 수 있었다.
