하천 제방 붕괴는 큰 피해를 초래하므로 하천 제방 상태의 변화를 감지할 수 있는 모니터링 시스템을 활용하여 이러한 재해를 예방하는 것이 사회적으로 매우 중요합니다. 제방사면의 붕괴를 조기에 탐지할 수 있는 가능성을 조사하기 위해 인공강우와 관입을 이용하여 실물규모 제방 붕괴모델을 붕괴시키는 실험을 수행하였고, 탐지시스템을 이용하여 제방상태의 변화를 측정하였다. 붕괴 중. 시스템은 센서 플레이트, 분산 광섬유 스트레인 센서 및 개인용 컴퓨터로 구성됩니다. 이 시스템을 사용하면 제방 경사면에서 토양의 움직임으로 인해 발생하는 힘에 의해 센서 플레이트에 생성된 신축이 플레이트에 고정된 감지 광섬유에 의해 변형으로 감지됩니다. 분산형 광섬유 변형률 센서는 광섬유를 따라 장거리에서 연속적으로 변형률을 측정할 수 있으므로 하천 제방과 같은 토목 구조물을 모니터링하는 데 적합합니다. 실험을 통해 센서판이 매설된 곳 부근에서 사면 붕괴가 진행되면 제방의 변화를 명확하게 감지할 수 있음을 확인하였다. 결과는 제방 경사면의 붕괴를 예측할 수 있는 가능성을 시사합니다.

Abstract: Since river levee collapse causes great damage, it is socially very important to prevent such disasters by using a monitoring system which can detect changes in the state of a river levee. To investigate the possibility of detecting the collapse of a levee slope at an early stage, we performed an experiment in which we used artificial rainfall and penetration to collapse a full-scale levee model, and measured the change in the levee state using a detection system during collapse. The system consists of sensor plates, a distributed fiber optic strain sensor, and a personal computer. With this system, the stretching produced in the sensor plates by the force resulting from the movement of the soil on the levee slope face is detected as strain by a sensing optical fiber fixed to the plates. Since the distributed fiber optic strain sensor can measure strain continuously and for a long distance along a fiber, it is suitable for monitoring civil structures such as river levees. The experiment confirmed that a change in a levee can be clearly detected when the slope face collapse progresses near the place where the sensor plates are buried. The results suggest the feasibility of being able to foresee the collapse of a levee slope.
