摘要

最近,由于全球变暖和气温异常,世界各地都出现了局地性暴雨,而大部分国土都是山区的韩国,山体滑坡等洪水灾害正在不断增加。因此,本文提到了在山区防止洪水破坏的结构之一的侵蚀控制坝的重要性,但由于混凝土构成的材料限制,大多数大坝需要替代。本文针对现有混凝土防淤坝存在的问题,研究了一种改进型开式防淤坝,以降低快速修复和维护成本。为此,利用商业有限元分析程序进行分析研究,对坝形和防漂结构进行实施,并计算极端环境条件下的外荷载,全面确认目标结构的安全性。

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