An Analytical Study for Safety Evaluation of Demolition-Assembled Permeable Steel Open-Type Erosion Control Dam

Abstract

Recently, localized torrential rains are occurring worldwide due to global warming and abnormal temperatures, and in Korea, where most of the land is composed of mountainous areas, flood damage such as landslides is continuously increasing. Accordingly, the importance of erosion control dams, one of the structures for preventing flood damage in mountainous terrain, is mentioned, but mostly dams need alternatives due to material limitations composed of concrete. In this study, an improved open-type erosion control dam was studied to reduce the cost of rapid recovery and maintenance based on the problems of the existing erosion control dam consist of concrete. For this purpose, an analytical study using a commercial finite element analysis program was conducted to implement the dam shape and drift prevention structure, and to calculate the external load under extreme environmental conditions to comprehensively confirm the safety of the target structure.
