碩士 === 國立中央大學 === 土木工程研究所 === 98 === This research discusses “scanline method” which is used in volume block proportion (VBP) for uncertainty. The major factor which affects the uncertainty of VBP is different scanline lengths. Kuo(2005) uses four kinds of representative volume element (RVE) with different outer edge shape and ellipse or the circular blocks connects the different length of the scanline by simple random sample to simulate VBP uncertainty. This research use the statistical sample point, the central limit theorem, and the length of computation for the uncertainty analytic solution, to explain the Kuo(2005) result of simulation. This research showed the analytic solution match the numerical simulation of Kuo(2005). For the in-situ data, we suggest that use analytic solution of this research to calculate the scanline method for measuring VBP uncertainty.
