Shale gas has become a significant resource play in the USA over the past few years and
companies are now evaluating the shale gas potential of many sedimentary basins …

This study presents the results obtained from laboratory tests carried out on different types of
clay-bearing rock collected from various parts of Turkey, to quantify the effects of water …

Every engineering structure, whether it's a building, bridge or road, is affected by the ground
on which it is built. Geology is of fundamental importance when deciding on the location and …

This paper presents the synthesized and characterized properties of Eagle Ford Shale (EFS)
based on the collected data and laboratory testing results from the canceled …

A series of clay shale specimens in equilibrium with various humidity conditions were used
to establish the water retention characteristics, the influence of suction on ultrasonic p-wave …

Clay-rich shales form the overburden in many sedimentary basins and the seals to
hydrocarbon accumulations in the subsurface. Their strength properties are not well …

Microstructural and mineralogical observations of claystones reveal the presence of clay
aggregates bonded by a skeleton of inert minerals such as calcium carbonate. The …

The unconfined compressive strength (UCS) of a rock is a basic parameter for many
characterization systems, strength criteria and calculation methods. It is well-known fact that …

The paper focuses on ground movements associated with tunnelling and deep excavations
in stiff to hard soils. The first part presents field data from case histories of earth pressure …

The paper examines some aspects of the hydromechanical behaviour of argillaceous hard
soils and weak rocks. After considering the wide variety of this class of materials, some …
