Analytical model for uncertainty characterization of fracture intensity measurement in rock massesFractured rock massThree-dimensional fracture intensityRepresentative elementary volumeAnalytical modelNumerical simulationThis paper presents an analytical model for quantifying the uncertainty of three-dimensional fracture...
This work develops a rock mass characterization of a limestone quarry in northern Spain based on a 3D model obtained by using photographs taken from an unmanned aerial vehicle (UAV) flight and structure-from-motion algorithms. This methodology permits to obtain photogrammetric information in a rapid...
摘要: This study proposed a rough-joint model to simulate the strength and deformability of rock joint under various loadings. The proposed model adopted the Barton model to consider the roughness effect of joint. To implement the rough-joint model in DEM关键词:...
At low in-situ stress, the continuity and distribution of natural fractures in rock mass predominantly control the failure processes. However at high in-situ stress, the failure process are affected and eventually dominated by stress-ind... 천대성,박찬,박철환,... - 《Tunnel & ...
Acoustic emission count is a commonly used acoustic emission characterization parameter that reflects the energy released from the coal or rock due to the process of internal crack formation and expansion. The level of acoustic emission count indicates the magnitude of the internal damage to the coal...
