  • 현재 2011년 10월 개통 목표인 경인 아라뱃길의 기반시설 공사에 일환인 영종대교 주변 수역에 선박 통항로가 재설정될 예정이다. 영종대교의 주변 수역에 설정될 통항로는 항로폭이 협소하고, 영종대교 주교각에 충돌방지공이 아직 설치되어 있지 않으며, 직선항로가 충분히 확보되어 있지 않은 상황에 있다. 이 연구에서는 영종대교 주교각에 충돌방지공이 설치완료되기 전까지 선박통항의 안전을 도모하기 위한 통항로의 통항 규칙 및 비상대응 매뉴얼을 제안하고자 한다.

  • In this study, field measurements were performed to analyze the effects of train types (AREX, AREX Express, KTX, KTX-Sancheon) and train speeds on the dynamic behavior of the direct fixation track structure on Yeongjong grand bridge by bridge type (truss bridge, suspension bridge). Based on field measurement results, the track impact factor and train running stability (coefficient of derailment, Rate of wheel load reduction, lateral displacement of rail head) are compared with domestic and foreign standards and regulations to influence the dynamic behavior of direct fixation track. As a result, the differences in the dynamic behavior of the direct fixation tracks by the type of bridges of Yeongjong bridge are not significant, but it was analyzed that these were more directly affected by the magnitude of the train load. Therefore, it is necessary to establish the reinforcement plan of the direct fixation track structure on Yeongjong grand bridge in consideration of the increase of the track impact factor and dynamic track force.

  • This paper presents schematically the monitoring system installed in Yongjong Bridge, a self-anchored suspension bridge located in the expressway linking Seoul and Incheon International Airport. Automatic measurement of instrumented civil engineering structures is now widely applied for behavior monitoring during construction in field as well as long-term monitoring for lifetime assessment of bridge structures. A representative example of results that can be acquired through structural health monitoring system is presented by means of data measured during a few years after the opening of the bridge. In order to effectively measure the tension force for hangers that have relatively short length or high tension force, a static tension measurement device has been explored. Newly equipped railway system on the existing bridge results in change of dead load, consequently dynamic characteristics have also been changed. This result can be detected by the monitoring system during and after railway construction.

  • Guss asphalt used in pavement of a steel deck bridge may cause severe stress and displacement on the bridge as it is treated using very high temperatures ranging from 220oC to 260cC. Therefore, it is critical to estimate the thermal effect of Guss asphalt on the steel deck bridge before the width and pattern of the unit portion are decided in order to minimize impact. In this study, we have conducted a series of numerical analysis of the upper road of Youngjong Grand Bridge, verified the feasibility of numerical value analysis by comparing the results with the data measured, and studied the thermal effects of Guss asphalt on the steel deck bridge according to temperature changes.
