Abstract

A method for estimating rock joint size distribution using contained traces length distribution from 3D cylindrical window survey was suggested. To reduce the numerical error, an improved technique was applied. The accuracy was verified by referring to Monte-Carlo simulation and it was found that the error can be decreased with suitable gamma values.

본 연구에서는 3차원 원통형 조사창에서의 양끝내포선 길이 분포를 이용하여 절리 직경 분포 추정을 수행하였다. 추정 결과의 수치적인 오차를 줄이기 위하여, 보조변수를 도입한 개선된 방안을 제시하였다. 몬테-카를로 시뮬레이션으로 검증한 결과, 보조변수의 변화에 따라 추정 분포의 진동이 줄어들어 오차가 크게 감소한 것을 확인하였다. 또한 절리 직경의 최적 분포 및 적정한 보조변수 값을 찾기 위한 알고리즘을 제안하였다.
