摘要:...3-m-diameter exploratory tunnel excavated in hard rock by an open tunnel boring machine (TBM). The study provides a methodology, based on photographic analysis, for the evaluation of the particle size distribution of debris produced by the TBM. A number of tests were carried o...

摘要:Rock slopes require geo-engineering evaluation to assess the instability of critical slopes leading to landslides particularly in Himalayan terrain where rocks are highly jointed, fractured and weathering prone. Interplay of discontinuities in the rocks coupled with other paramet...

摘要:Abstract(#br)We review the existing methods for evaluating the hydraulic conductivity of a rock mass. Rock mass permeability may be assessed using empirical, analytical and numerical approaches. Empirical methods use data from in situ field tests to derive the relationship betwee...

摘要:Abstract(#br)Direct contact measurements for rock mass discontinuities are generally difficult to perform, time consuming, biased, and often dangerous. This paper presents an automatic characterization method for rock mass discontinuities that uses 3D point clouds, which can be o...

摘要:Because of the complex geological structure, determination of the field mechanical parameters of the columnar jointed rock mass (CJRM) was a challenging task in the design and construction of the Baihetan hydropower plant. To model the mechanical behaviour of the CJRM, uniaxial c...

摘要:... Since many GPR applications are performed in rock mass with non-homogeneous discontinuous nature, errors in estimating a bulk velocity of propagation or dielectric constant are possible. This paper presents a new in-situ GPR test for mapping the dielectric constant variabilit...

摘要:An accurate characterization and modelling of rock mass geomechanical heterogeneity can lead to more efficient mine planning and design. Using deterministic approaches and random field methods for modelling rock mass heterogeneity is known to be limited in simulating the spatial ...

摘要:Abstract(#br)The prediction of rock mass cavability is needed in the design of block caves to estimate the undercut size required to achieve continuous caving. The cavability of the rock mass will control mine design and economic issues for a given geological environment and is a...
