초록

최근 이상 기후에 의한 국지성 집중호우, 폭염 등의 빈번한 발생으로 통합적인 빗물관리 시스템의 도입이 필요하다. 따라서, 빗물침투와 저류를 동시에 구현함으로써 집중강우에 대한 홍수방지 뿐 아니라, 빗물침투를 통한 지하수위를 확보할 수 있는 경제적이며 친환경적인 빗물침투저류시설의 개발이 요구되고 있다. 본 연구에서는 황토를 포함한 친환경 무기질 결합재를 이용하여 만들어진 친환경 빗물침투저류시설의 구조적 안전성에 대해 검토했다. 상시하중과 부가적인 수직하중을 고려한 정적해석과 지진 스펙트럼을 고려한 동적해석을 수행했다. 그 결과, 본 연구에서 개발한 친환경 조립식 빗물 침투형 저류시설은 기존의 PE 블록 빗물저류시설과 비교하여 동일 하중조건 및 지진조건 하에서 발생되는 최대응력은 약 68.1% ~ 75.4%, 최대변위는 약 0.9% ~ 9.6% 수준으로서 우수한 구조적 안정성을 확보하는 것을 확인할 수 있었다.

Recently, due to the frequent occurrence of localized torrential rains and heat waves caused by abnormal climates. For this reason, it is necessary to develop an economical and eco-friendly rainwater detention facility that can secure the groundwater level through rainwater detention as well as flood prevention against concentrated rainfall by simultaneously implementing rainwater permeation and storage. In this study, the structural safety of an eco-friendly rainwater infiltration type detention facility made using eco-friendly inorganic binders including red clay was examined. Static analysis considering the constant load and additional vertical load and dynamic analysis considering the seismic spectrum were performed. As a result, it was found that the eco-friendly prefabricated rainwater infiltration type detention facility developed in this study has a maximum stress of about 68.1% to 75.4% and a maximum displacement of about 0.9% to 9.6% under the same load and seismic conditions compared to the existing PE block rainwater detention facility. It was confirmed that the eco-friendly prefabricated rainwater infiltration type detention facility secured excellent structural stability.
