Abstract

Although standards related to falling stone facilities are established in Korea, the absorption energy of the rockfall prevention net is evaluated from the passage of rockfall and destruction of the rockfall prevention net on field test. The existing PVC coating net does not sufficiently suppress the rockfall load and tears frequently occur, and a high-strength wire rockfall net was developed to prevent. In this study, the performance was analyzed through field tests of the existing PVC coating net and the developed high-strength rockfall net (1,000 MPa, 2,000 MPa).

High-strength rockfall net (1,000 Mpa, 2,000 Mpa),

Field test

국내에는 낙석시설 관련 기준이 마련되어 있지만, 낙석방지망 흡수에너지의 경우 실물 시험을 통해 낙석의 통과여부 및 낙석방지망 파괴 여부로부터 흡수에너지를 평가하게 되어있다. 기존의 PVC 코팅망이 낙석 하중을 충분히 억제하지 못하고 찢어지는 현상이 빈번하게 발생하는데, 이를 방지하기 위해서 고강도 선제 포획망을 개발하였다. 본 연구에서는 기존의 PVC 코팅망과 개발된 고강도 선제 포획망(1,000MPa, 2,000MPa)의 현장 테스트를 통해 성능을 분석하였다.
