Elevated temperature effects on swelling pressure of compacted bentonite
Deep Underground Science and Engineering, EarlyView.We present a set of new experimental investigations on the effects of elevated temperature on the swelling pressure development of compacted bentonite. This research was motivated by an emerging interest in using bentonite as a plug material in oil and gas well abandonment.

Deep Underground Science and Engineering, EarlyView.Upon conceptualization of structural behavior, foundations in terms of their form are divided into linear (1D), planar (2D), and volumetric (3D). Regarding the load transfer mechanisms, linear foundation systems are considered vector‐acting, planar foundations are divided into section and surface‐acting, and volumetric ones are recognized as block ...

Geoarchaeology, Volume 38, Issue 1, Page 35-56, January/February 2023., 2023 Abstract The effects of the Younger Dryas (YD) fluctuation on Late Pleistocene hunter‐gatherers' settlement and subsistence systems in the southern Alps are poorly known. This is primarily due to the scarcity of archaeological sites dating from the YD, in contrast with the extensive evidence available from the lateglacial interstadial and the early ...

Stress analysis of crack characteristic of anthracite under dynamic loading
Deep Underground Science and Engineering, EarlyView.In this article, the dynamic compression test of anthracite under five strain rates is carried out, the evolution law of three kinds of crack characteristic stress is analyzed, and a prediction model of the crack characteristic stress threshold considering the strain rate effect is established. Then, the rationality of crack characteristic stress under

Deep Underground Science and Engineering, EarlyView.In this article, the finite element method‐smoothed particle hydrodynamics adaptive coupling algorithm is applied to numerically simulate and analyze the dynamic response of the slit tube and the crack propagation under high in situ stress. The dynamic response of the slit tube mainly exhibits radial response in the vertical direction of the slit and ...
