CORRECTION OF DISCONTINUITY SPACING BIAS CAUSED BY FINITE LENGTH SCANLINE SURVEY
（Testing Center, Central South University of Technology, Changsha 410083）
Abstract:For discontinuity spacing based on negative exponential probability density, a weight function method used for correction of sampling bias caused by finite scanline was proposed. The result showed that relative error improves from 0.5% to 40%. This makes it possible to estimate discontinuity spacing of rock-mass using short scanline.
Key words: discontinuity spacing negative exponential probability density scanline survey
