Abstract

The inappropriate hydraulic design criteria on the new revetment technique for the ecological river restoration project happens to lead to economic loss during the flood season. In this study, the hydraulic stability of the developed non-toxic revetment was evaluated at a maximum discharge of 3.0 m3/s and a maximum velocity of 3.0 m/s in a real scale experimental channel. The vertical movement of the non-toxic revetment block was in the range of ±3 mm in the experimental conditions. The results show that the non-toxic revetment block was sufficiently hydraulically secured.

최근 생태하천 복원 사업용으로 개발된 호안 공법에 대한 수리학적 설계기준이 부적절하여 이 공법이 적용된 하천에서 홍수기에 큰 경제적 손실을 유발하고 있다. 본 연구에서는 생태복원용으로 개발된 무독성 호안 블록을 실규모 수로에 설치하여 최고 유량 3.0 m3/s, 최고 유속 3.0 m/s에서 수리적 안정성을 평가하였다. 설치된 무독성 호안 블록은 실험 조건에서 상하 ±3 mm 정도로 미미하게 이동하였다. 그러므로 실험에 적용한 무독성 호안 블록은 고유속에서 대규모 이동, 블록 파괴, 침상·침하 등이 나타나지 않는 것으로 보아 충분한 안정성을 확보한 것으로 판단되었다.
