Abstract

Recently, disasters caused by extreme weather and the damage caused by them are increasing worldwide. The interest in disasters, such as earthquakes, typhoons, and ground subsidence, is increasing in Korea. Korea has enacted a special law based on disaster management, and has built monitoring systems for individual facility units by building precision sensors and related systems to measure the displacement status of long bridges and high-rise composite buildings. On the other hand, the application of a real-time monitoring system is insufficient for slopes, open-pit mines, small and medium structures due to weather, measurement methods, cost, and constant monitoring difficulties. In this study, the displacement monitoring method using the total station was studied and the applicability was suggested through the experiment. Through the research, the concept and operation flow of a monitoring system that can measure the displacement of the terrain or the structure using the total station was presented. The monitoring system allows the user to select the location and operation method of the equipment so that the equipment can be installed according to the site situation, and set the number of observations, the period, and the observation range of the object. Using the experiment on the monitoring system, the station was monitored with precision within 5mm, and it was suggested that the displacement of the object can be monitored using the total station. Further research will be needed to assess the applicability of monitoring to real slopes and structures.

최근 기상이변으로 인한 재해가 전 세계적으로 증가하고 있으며, 세계적으로 재해로 인한 피해가 커지고 있어 국내에서도 지진, 태풍, 지반침하 등 재해에 대한 관심이 높아지고 있다. 우리나라는 재난관리에 의한 특별법을 제정하고, 장대교량 및 초고층 복합건축물은 시설물의 변위상태 측정을 위해 정밀센서와 관련 시스템 등을 구축하여 개별 시설물 단위의 모니터링 시스템을 구축하도록 하고 있다. 하지만 사면이나 노천광산, 중, 소규모의 구조물에 대해서는 기상, 측정방법, 비용, 상시 모니터링의 어려움으로 인해 실시간 모니터링 시스템의 적용이 미흡한 실정이다. 이에 본 연구에서는 토털스테이션을 활용한 변위 모니터링 방안을 연구하고, 실험을 통해 적용성을 제시하고자 하였다. 연구 결과 토털스테이션을 이용하여 지형이나 구조물의 변위를 측정할 수 있는 모니터링 시스템의 개념과 운영 흐름을 제시하였다. 모니터링 시스템은 현장상황에 따라 장비를 설치할 수 있도록 장비의 위치 및 운용 방식을 선택하고, 대상물에 대한 관측 횟수, 주기, 관측범위 등을 설정할 수 있도록 하였다. 모니터링 시스템에 대한 실험을 통해 5mm 이내의 정밀도로 측점을 모니터링 하였으며, 토털스테이션을 이용한 대상물의 변위 모니터링이 가능함을 제시하였다. 향후, 추가적인 연구를 통해 실제 사면이나 구조물에 대한 모니터링의 적용성을 제시할 수 있을 것으로 기대된다.
