A series of uniaxial compressive tests were carried out on rock-like brittle specimens with
pre-existing edge-opened cracks to investigate crack propagation characteristics using the …

In recent years, shale gas has become an important energy source due to its abundant
reserves. Due to their extremely tight initial properties, shale gas reservoirs require the use …

Layered shales exist widely and are often encountered during shale gas development.
However, the mechanical response of layered shales is significantly affected by the …

The special mechanics of inclined stratified jointed rock may cause unexpectedly surface
settlement. This paper studies the special rock condition with analyses of discrete element …

The displacement discontinuity method (DDM) has been widely used for large-scale
engineering problems, eg, hydraulic fracturing related to metal mining and hydrocarbon …

This paper outlines a two-dimensional displacement discontinuity method (DDM) for
transversely isotropic elastic materials and a direction-dependent criterion for fracturing in …

Jointed rock masses with different orientations and spacings are widely exposed in rock
engineering applications, such as underground caverns, slopes, and tunnels, which …

A conjugate jointed rock mass (CJRM) is a rock mass with two sets of intersecting joints
formed from intact rock under shear. Its mechanical properties and excavation-induced …

This paper uses the displacement discontinuity method, one of the boundary element
methods, to solve two major engineering problems. The first one addresses the safe design …
