초록

방콕(태국) 등 동남아시아 도시 홍수의 경우 열악한 배수시설로 포장된 도로를 따라 광대한 도심지역이 저수위 홍수에 침수되고 있다. 모래가 부족한 도심지의 경우 모래주머니 등 기존 침수방지 방법은 유효하지 않으므로 인공적인 침수방어 구조물을 설치할 필요가 있다. 이와 관련하여 유럽 및 북미 일부 선진국을 중심으로 개발된 침수 월류방어장비들은 고가에 복잡한 시공성을 가지고 있어 동남아시아 지역에 저변을 확대하기 어려운 상황이다. 따라서 저가 및 단순 고기능형 도심형 홍수임시차수시스템(FRDS)을 개발할 필요가 있다. 이에 본 연구에서는 FRDS의 개요 고찰, 국내외 개발 동향 분석, 개발 니즈 및 방향 제시 등을 통해 동남아시아에 적용할 수 있는 FRDS를 개발하였다. 개발한 시스템은 한국건설생활시험연구원 서산 옥외실증시험센터에서 누수율변형 시험 및 내충격성 시험에 관한 KS 성능평가를 실시하였으며, KS F 2639(누수율 변형 시험)과 KS F2236(내충격성 시험) 기준을 통과하였다. 본 연구결과는 홍수재난과 관련하여 동남아국가 도시홍수에 적용할 뿐만 아니라, 국내 홍수빈발지역 및 주요시설 등에 활용할 수 있을 것으로 판단되며, 도시홍수와 관련하여 주요지자체 및 시설물 관리기관의 과학적 능동적 대응을 유도할 수 있을 것이다.

A large urban region in Bangkok, Thailand is often inundated due to shallow water floods along the paved roads that have poor drainage facilities, and that can cause urban flooding. Existing methods, including using sand bags are not effective to prevent flooding in urban areas where the amount of sand is not sufficient. Thus, it is necessary to install artificial flood defense structures. However flooding and overflow defense equipment, which was developed in some advanced nations in Europe and in the USA, is highly expensive and complex construction methods are needed, therefore they are not suitable to be used in Southeast Asia. Thus, it is necessary to develop a flood rapid defense system(FRDS), which is inexpensive and simple to build, but is also highly functional. Thus, this study developed an FRDS that can be applied to Southeast Asia through the careful study of FRDS overviews, an analysis on the development trends in Korea and overseas, and the proposal of development needs and directions of the region. For the system developed, Korean Standards(KS) performance evaluations on leakage ratio deformation tests and impact resistance tests were conducted at the Outdoor Demonstration Test Center(Seosan) in the Korea Conformity Laboratories(KCL) and the system satisfied the standards of KS F 2639(leakage and deformation test) and KS F 2236(impact resistance test). The present study results can not only be applied to urban floods in Southeast Asian nations to cope with flood-related disasters, but also be utilized in flood prone regions and for major facilities in Korea. They can also induce scientific and pro-active responses from major local governments and facility management organizations in relation to urban floods.
