Estimation In-Situ Rockfall Block Weight Distribution Using Scan-Line Survey Results and Examination its applicability in Practical Rockfall Analysis

선조사 결과에 의한 실제낙석무게분포의 추정과 설계적용성 검토

Up to now, practical engineers applying simplicity value of rockfall block weight suggested in design manual without considering in-situ rockfall block weight which reflect joint characteristics. However, the size of rockfall block varies with joint spacing of discontinuities and influences over rockfall analysis results. In this paper, we estimate realistic rockfall block weight distribution using statistical invariances of joint spacing derived from scan-line survey result. And, we study whether this distribution is applicable in practical rockfall analysis directly. As the results of this study, rockfall analysis results that using rockfall block weight distribution estimated from scan-line survey show resonable and realistic outcomes.
