... and Villar, 2006; Sugita et al., 2005). In contrast, the compacted blocks assembly is applicable in the core area of barrier due to its high mechanization and fast assembling speed. The geometry, density and water content of blocks can be adjusted according to the actual construction condition. However...

... Abstract Discontinuum Mechanics is based on two foundations: the idealization of the internal structure of substances, and the principle of the arithmetic mean value. For a linear discontinuum, the methods of Crystallography are used to describe their structure, in which nodes stands...

... Abstract A continuum damage mechanics (CDM) based constitutive model has been developed to describe elastic, plastic and damage behavior of rock during drilling. In addition to inelastic deformations, this model incorporates rock anisotropies like toughness anisotropy due to the bedding planes...

Drill hole deviation results from the cumulative effects from both drilling mechanics and rock mass conditions. Once a hole has initiated the deviation trajectory, it is difficult to rectify drill...
