[21년01월] 6. 고속도로 인터체인지 연결로 운영속도(V85)조사 및 분석에 관한 연구 2021. 1. 18. 20:21 Geometric standards applied to road design in Korea are established based on design speed. However, after examining the operating speed (V85) of a car driving an actual highway interchange ramp, the speed of the vehicle is significantly above the design speed, and due to the large variation in the speed of the ramp, the highway interchange is considered a dangerous area for traffic safety. There..
[21년01월] 5. 아스팔트를 이용한 마찰증대 매트의 기술개발 2021. 1. 12. 20:47 Recently, the environmental impact on port facilities such as Quay and Breakwater is gradually increasing due to extreme weather change caused by global warming. Accordingly, the port facilities are designed to secure stability against high waves by increasing their own weight or increasing the frictional force of the bottom in order to enhance the safety factor. Since the method of improving th..

HEC-6 모형을 이용한 유사량 공식에 따른 하상변동 민감도 분석 - 낙동강 하류를 대상으로 2021. 1. 12. 15:22 In this study, the sensitivity analysis of bed changes due to the various sediment transport equations have been conducted for 80km reach of the Lower Nakdong River using the HEC-6 which is one dimensional numerical model. The bed elevation changes according to the different sediment transport formulas were compared and analyzed quantitatively. As a result of the numerical simulation, the final ..
[21년01월] 3. 파키스탄 Jhelum 강의 퇴적물 수송 분석 및 준설 계획 2021. 1. 11. 20:08 The riverbed of the Jhelum river at the powerhouse location was rised is that the width of the river became narrow due to the construction of the access bridge and newly built left bank around the bridge. Moreover, it can also be guessed that the dumped materials played an important role as the river bed was being increased by deposits, durinvg the process of the river flow channel change with t..
[21년01월] 2. 유기물 부하에 따른 Anaerobic digestion 및 Bio-electrochemical anaerobic digestion의 박테리아 군집 2021. 1. 11. 07:00 This study compared organic matter removal and methane production performance of AD and BEAD reactors by gradually increasing food waste OLR. Bacterial communities in reactor bulk solution were measured at each OLR to investigate the effect of voltage supply to bacterial species change in bulk solution. The BEAD reactor maintained stable levels of COD removal and methane production at 6.0 kg/m3･..
