Abstract
Purpose: It is essential to have a response technology to prevent the diffusion of oil contaminant due to spill accidents in areas with a high possibility of contamination. Therefore, this paper described the results of an experimental research to analyze the relationship between the barrier performance and spectral information of the developed liner. Method: Lab-scale model experiment was conducted to evaluate the barrier performance of the liner according to the mixture conditions of the reactive material and an experiment was conducted to obtain spectral information. The barrier performance of the liner was evaluated by the permeability coefficient of the model ground, and the results were analyzed in relation to the maximum reflectance of the reactive material. Result: The liner had an impermeable characteristic as the composition ratio of polynorbornene increased. In addition, the maximum reflectance of the reactive material decreased as the composition ratio of polynorbornene decreased. Conclusion: The experimental results showed that the maximum reflectance of the reactive material according to the mixture conditions can be predicted by a quadratic function with high reliability. Based on these results, it was evaluated that it is sufficiently possible to infer the mixture conditions of the reaction material for optimizing the barrier performance of the liner.

연구목적: 오염물 발생 가능성이 농후한 지반 내에 오염물 유출사고로 인한 확산을 차단하기 위한 사전 대응기술이 필요하다. 따라서 본 연구에서는 개발된 라이너에 대한 차단 성능과 분광정보의 관계를 분석하기 위한 실험적 연구를 수행하였다. 연구방법: 반응재료의 배합 조건에 따른 라이너에 대한 차단 성능 평가를 위한 실내 모형실험 및 분광정보 획득을 위한 실험을 실시하였다. 그리고 배합 조건별 라이너의 차단 성능을 지반의 투수계수로 평가하였으며, 이 결과를 반응재료에 대한 최대분광반사율과의 관계로 분석하였다. 연구결과: 라이너의 차단 성능 실험 결과, 반응재료의 주 반응제인 폴리노보넨의 구성비가 증가할수록 라이너는 불투수성의 특성을 갖는 것으로 분석되었다. 그리고 반응재료의 최대분광반사율을 평가한 결과, 폴리노보넨의 구성비가 감소할수록 최대분광반사율도 감소하였다. 결론: 배합 조건에 따른 반응재료의 최대분광반사율은 높은 신뢰도를 확보한 이차함수로 예측이 가능하고, 이를 라이너의 차단 성능 최적화를 위한 반응재료 배합 조건의 유추가 충분히 가능한 것으로 평가되었다.
