Abstract

In the present study, a face safety monitoring system was developed that will enable judging collapse risks on faces during tunnel construction to secure workers' safety. This system enables detecting abnormal behaviors of faces by analyzing the displacement of faces measured in real time using the x-MR control chart technique. In addition, an algorithm to judge false alarms was developed so that abnormal behaviors of faces and errors occurring in the process of work can be distinguished from each other by comparing the number of measured values exceeding the management criteria and moving range k. The results of the present study are applicable to real-time monitoring of behavior on the face in dangerous ground sections to minimize damage to workers.

본 연구에서는 터널 시공 중 굴진면에서의 붕괴 위험을 판단하여 작업자의 안전을 확보할 수 있는 굴진면 안전감시시스템을 개발하였다. 이 시스템은 실시간으로 측정되는 굴진면 변위를 x-MR 관리도기법으로 실시간 분석함으로써 굴진면의 이상 거동을 감시할 수 있다. 또한 관리 기준을 초과하는 측정치의 개수와 이동 범위 k를 비교하여 굴진면의 이상 거동과 작업 과정에서 발생하는 오류를 구분할 수 있도록 오경보 판단 알고리듬을 개발하였다. 본 연구결과는 위험지반 구간에서의 굴진면의 실시간 거동 감시에 적용되어 작업자의 피해를 최소화 할 수 있을 것으로 판단된다.
