초록

본 연구는 소규모 충적하천의 안정 하폭 및 수심의 결정기법인 Cheema 등의 방법을 개선한 것으로, 이 기법은 기존 방법과는 달리 제방의 일체 파괴와 전단 파괴에 대한 안정성을 고려할 수 있는 효과적인 방법이다. 실제 하천의 관측 자료에 적용시켜 본 결과, Cheema등의 방법은 50m이하의 하폭을 가진 충적하천일 경우에만 적용이 가능했으나, 본 연구에서 제시한 개선된 방법은 하폭 200m이내의 충적하천의 안정하폭 및 수심을 양호하게 산정하였다. 따라서 본 연구에서 제시된 기법은 실제 충적하천 횡단면의 설계시 유용하게 적용될 수 있을 것으로 판단된다.

In this study, the method of Cheema et al., which is used to decide stable width and depth of the small alluvial rivers, is improved to consider the stability of mass failure and shear failure of the bank effectively. This improved method is applied to the actual rivers, and this result is compared with the result of the method of Cheema et at.. While the method of Cheema et al. could be applied to the alluvial rivers with channel width below 50m, this improved method shows good results in estimating stable width and depth up to 200m. Therefore, this improved method can be suggested as an effective technique in the profile design of small alluvial rivers.
