There have a lot of marine accident due to the increasing transportation by sea in accordance with economy growth. Accordingly, w are fully aware of the importance of the development of safety control System so that may prevent the sacrifice of life and disasters on the sea. The objective of this research in to investigate the more effective system by establishing the prevention of safety accident and marine information system as a national project.

신규 통신 서비스 제공을 위해서는 이를 수용하기 위한 전송망 회선을 필요로 한다. 전송망 회선 공급을 위해 기존 전송시설 여유수, 증설 가능수, 신설되어야 하는 시설수를 전송구간별로 검토 분석하여야 하나 전송망 구조가 복잡하고 연간 전송망 회선 수요가 수백구간에 달해 수작업 처리가 불가능하다. 이를 해결하기 위해, 현재의 전송시설 데이터를 분석하고 수요 전송회선을 수용하기 위해 필요한 전송시설 물량을 산출하는 전산시스템(TNePS)을 개발하였다. 본 고에서 전송망 공급계획 수립 업무와 TNePS 시스템의 주요기능 등에 대해 기술한다.

대규모 토목공사에서 토량환산계수는 공사물량 및 공사비에 미치는 영향이 크므로 합리적인 토량환산계수의 설계가 요구된다. 그러나 토량환산계수의 산정에 있어서 선정시험에 의한 결과치가 아닌 통상적으로 사용하고 있는 설계기준서에 제시된 값을 적용함으로써 정확한 잔토 및 부족토량의 산정에 있어서 많은 어려움이 따르며, 이러한 경우 현장여건에 적합한 대규모 현장시험을 실시하여 토량환산계수를 산정하는 것이 바람직하다. 또한 대규모 현장시험에 있어서 굴착부분의 체적은 토량환산계수 산정에 있어 매우 중요한 요소가 된다. 따라서, 본 연구에서는 대규모 현장을 대상으로 절 성토부 풍화암의 굴착부분의 체적을 정확히 산정하기 위하여 수치사진측량기법을 적용하였으며, 이를 Total Station에 의한 측량방식과 비교 분석하였다. 그 결과, 교차에 대한 상대정확도는 평균 0.5%로 산출되었으며, 체적에서 0.5%의 상대정확도는 길이 측정에서 0.17% 상대정확도에 해당되므로 정확한 측량이라 판단된다.

In general bathymetric surveying is the method which gets depth. The water depth on chart is generally measured by a 200Khz frequency echo-sounder. In this study the thickness of the floating silt-clay was measured by a duel frequency sounder using 33Khz and 200Khz. This study shows the method of measuring the volume of the floating silt-clay in dredged basins dredged basin. After this surveying RI test was performed for verifying the existence of the silt-clay.
