Terra Nova, 23, 145–161, 2011 Abstract The hydrogeology of superficial (∼ 0–100 m bgl)
Hard Rock Aquifers (HRA; ie plutonic and metamorphic rocks) has so far been dominated by …

Water is a crucial factor that influences the mechanical behavior of rock and can induce
failure. The aim of this study was to investigate the effects of water content and water …

Underground rock structures are frequently subjected to water erosion and dynamic
disturbance simultaneously. Herein, in order to study the coupled effects of water and high …

The mechanical behavior of rock is significantly affected by water. To further study the
influence of water on the mechanical behavior of rocks, uniaxial compressive loading …

A reduction of uniaxial compressive strength (UCS) by the presence of water has been
ascertained in many sedimentary rocks and even some metamorphic rocks experimentally …

Hydraulic fracturing is a combined process of mechanical and hydraulic behavior due to in
situ stress, well bore pressure, fluid infiltration in the rock mass. The initial state of …

A suite of true triaxial tests were performed on Castlegate sandstone to assess the influence
of the intermediate principal stress on mechanical response and failure. Five independent …

We conducted true triaxial compression tests on specimens prepared from two siltstone core
sections, one above and one below the Chelungpu Fault, Taiwan. For different constant σ2 …

This paper summarizes the true triaxial experiments we conducted on core received from the
San Andreas Fault Observatory at Depth (SAFOD). The SAFOD project was part of the …

The magnitude and direction of geo-stress undergoes complex changes following
disturbance by artificial excavation in underground engineering. Tests were conducted …
