We advance the method of Hudson and Priest (Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts 20 (1983) 73–89) to develop a method for a curved scanline to be used to predict the numbers of fractures that would be observed in a

A two-dimensional model of fracture permeability normal to bedding in layered rock with orthogonal, bed-delimited fractures is investigated. Steady-state, saturated laminar flow is assumed. Permeability is assumed to be a function of apertures and fl

We introduce new estimators for fracture trace intensity, trace density and mean trace length that exploit the use of circles as efficient sampling tools. A fracture trace is the commonly observed surface expression of a fracture, i.e. the intersecti

Although window samples of fracture traces are widely recognized to be length-biased and censored, they are often the best source of data for inferring statistical parameters of fracture sets. This paper presents new estimators for mean fracture trac

In this paper we develop correction factors for orientation bias when sampling rock fractures with a borehole. For a borehole with zero radius we obtain Terzaghi's result for scanline sampling: otherwise the appropriate correction factor may differ s

Although wedge and plane sliding stability analyses are well established in the geotechnical literature, certain geologic environments produce blocks which cannot be adequately modelled as either wedges or plane slides. An example is blocks forming i

The traditional soil nailed structure incorporates grouted or driven nails, and a wire mesh reinforced shotcrete facing to increase the stability of a slope or wall. This paper describes the construction and monitoring of a full-scale demonstration o

Keyblock size distributions are of fundamental importance in many branches of applied rock mechanics, including tunnelling, mining and rock slope engineering. While strongly dependent on discontinuity parameters such as spacing, persistence (or size)

Joint intersection points are of interest because of their relations to the blocks that comprise the rock mass. Removable tetrahedral blocks, for example, have exactly one joint intersection point at the interior block apex; thus joint intersection p

A method for evaluating the effects of joint orientation variability on block theory analysis is presented. Ramsay's solution for the range of the direction of the line of intersection of two variable planes is generalized to joint sets with unequal
