초록

제방은 기본적으로 물이 넘치지 않도록 하기 위하여 조성되는 구조물이다. 개발된 제방보강 기술은 바이오폴리머와 골재를 혼합하여 제방의 붕괴로 발생되는 대규모 재난을 방지하기 위한 기술로 제방의 세굴 및 붕괴 등을 억제하는데 목적이 있다. 개발된 기술은 호안 사면 등에도 활용이 가능하지만 시공성이 수월하여 월류파괴에 대한 대응 기술로 적용하기 용이하다. 개발된 기술을 현장에 적용하기 위해서는 기술의 안전성을 확보해야 하므로 현장시범사업 등 실제 적용에 대한 연구가 필요하다. 하지만 월류 파괴는 현장에서 시범사업을 수행할 수 없으므로 본 연구에서는 실규모 실험을 통해 현장 적용성 연구를 수행하였다. 실규모실험은 안동에 위치한 하천실험센터에서 수행하였으며, 인위적인 월류를 통하여 제방 세굴 및 붕괴 상황을 검토하였다. 실험결과 개발기술이 월류파괴에 대해 대응 가능하고 붕괴를 억제할 수 있는 기술로의 실증을 수행하였다.

Developmental technique is mixed bio-polymer and riprap to protect the breaking of a levee. Purpose of new technique is restraint from scour and failure of bankside. Technique of this research can apply shore protection and embankment overflow reinforcement works. Because This technique is easy for construction. In order to apply the technique in fields, It is need to conduct the test-bed or real scale experiment study for stability-guaranteed. In case of embankment overflow reinforcement works, It is difficult to conduct test bed in the field. Real scale experiment was conducted in River Experiment Center. Purpose of real scale experiment is to reappear disaster scene by embankment overflow and verify restraint from scour and failure about the technique. In this experiment results, We can find the strength effect of mixed bio-polymer and riprap.
