Geotechnical design with apparent seismic safety factors well-bellow 1 [PDF]

, 2014
The paper demonstrates that whereas often in seismic geotechnical design it is not realistically feasible to design with ample factor of safety against failure as is done in static design, an "engineering" apparent seismic factor of safety less than 1 ...

A rock brittleness index based on the postpeak energy release rate and damage surface characteristics for brittle hard rock

Deep Underground Science and Engineering, EarlyView.
This study examines energy evolution in rock rupture via triaxial direct shear tests, exploring the impact of confining pressure and temperature on fracture surface randomness. A novel energy‐based brittleness index is proposed, validated experimentally, and compared with existing methods for reliability and accuracy.

Investigation of Lateral Stress Relief on theStability of PHI = 0 DEG Slopes Using Laboratory, Fracture Mechanics, and Finite Element Method Approaches [PDF]

, 2011
Total stress analyses of purely cohesive cut slopes utilize the undrained shear strength for slope stability analyses. These slopes can have an in-situ lateral earth pressure that is greater than the vertical pressure.

Numerical and experimental study on P‐wave propagation across a rock joint with different orientations

Deep Underground Science and Engineering, EarlyView.
Joint orientation significantly affects P‐wave velocity, with the highest velocity at zero‐degree angles, decreasing to 30° as the angle increases. The velocity increases slightly from 30 to 45 degrees but sharply decreases from 45 to 90 degrees. Abstract Determination of the required parameters in different science contexts using the ultrasonic wave ...

Design Considerations for Ash Pond Dyke Construction in Hilly Terrain for High Concentrated Slurry Disposal: A Case Study [PDF]

International Journal of Mining and Geo-Engineering
Designing an ash pond for High Concentrated Slurry Disposal (HCSD) in hilly terrains poses a unique set of challenges. In such regions, the availability of barren land adjacent to the project sites is limited, making it difficult to locate suitable sites

Set-up effects of piles in sand tested in the centrifuge [PDF]

, 2014
The bearing capacity of piles increases over time. Research has shown that this is caused by an increase in shaft friction combined with a constant or only slightly increasing base capacity.
