Journal of Geotechnical Engineering, 1983
This paper describes the results of two full scale rock socket load tests conducted in conjunction with the foundation design of a sulfur dioxide removal plant located at the Four Corners Generating Station near Farmington, New Mexico. The tests were conducted in a soft shaley sandstone with an average unconfined compressive strength less than 1,500 ...

Stress measurements in soft rocks
Engineering Geology, 2003The objective of this paper is to demonstrate that accurate and reliable in situ stress measurements can be performed in soft rocks. A quick overview of the mechanical behaviour of soft rocks is presented. After reviewing stress measurement techniques that have been used in soft rocks, the modified doorstopper technique is presented and the advantages ...

On the Measurement of the Tensile Strength of Soft Rocks
Rock Mechanics and Rock Engineering, 2005This paper reports on a comparative study of various types of experimental tests for measuring the tensile strength of rocks and rock-like materials. A critical assessment is presented of some widely used laboratory techniques on the basis of experimental data from the literature and from the laboratory investigation performed in this study. Tests were

<p>In this work, the mechanically induced compaction process in highly porous rocks is studied with experimental investigations and constitutive modeling. The focus of the study is on the influence of the inherent anisotropy on the mechanical properties. From a practical point of view, such behavior is of particular interest when

Soft Rock Studio: Exploring a "Soft Systems" Approach to "Artificial Rock"
2022This paper discusses a study aimed at shifting disciplinary norms in construction materials. The study, conducted in a graduate level design-build studio, approached precast concrete construction through the lens of “artificial rock”: a composite material that can use cement, sand, aggregate, and reinforcing supplements and alternatives like flax ...

International Journal of Mining and Geological Engineering, 1988
Soft rock pillars can be designed by several methods available in the mining literature. All of these methods include the effect of shape, or geometry, on the average strength of specimens and pillars. All of the pillar design methods include some measurement of the strength of specimens of the pillar rock.

Correlation of Soft Rock Properties
2019Soft rocks are a critical type of natural material, due to their low strength, and sometimes problematic behavior in engineering works, since they may crumble, swallow, slake, contract, and so on. It is not uncommon do adopt too much conservative parameters for these types of rocks, due to the insufficient knowledge of their properties. Improving their
