Abstract

This study is focused on developing a technology to prevent high-strength wire net from expanding damage due to insufficient performance of the existing PVC coating net. For the test method, reference was made to ISO 17746, an international standard. In addition, as a result of referring to the test criteria, a wire net was fabricated with a width of 1,000 mm or more a size of 1 m2 sample. load-displacement curve of the test results was compared to analyze how much performance was improved compared to the existing PVC coating net.

본 연구는 기존 PVC코팅망의 성능 부족으로 인한 찢어짐으로 인근 피해 확대를 방지하기 위하여 고강도 선재 포획망을 제작하여 이를 방지하기 위한 기술을 개발하기 위해 시험을 진행한 것이다. 시험 방법은 국제 기준인 ISO 17746:2016을 참조하여 steel wire ring panel과 steel wire rope net panel, roll에 대한 장력시험(인장시험)에 대한 사항의 규정을 따라, 고강도 선재 포획망의 장력시험 시 고강도 선재 포획망 시편은 폭 1,000mm 이상, 최소 시편크기 1.0m2를 제작하였다. 시험결과의 하중-변위 곡선을 비교하여 기존의 PVC 코팅망 보다 성능이 얼마나 향상되었는지를 분석하였다.
