Development of random mesostructure generating system of soil-rock mixture and study of its mesostructural mechanics based on numerical test

, 2009
The mesostructure characteristics significantly affect meso-failure evolution mechanism and the macro-mechanical characteristics of soil-rock mixture (S-RM) under external forces.

Mechanisms of Shallow Rainfall-induced Landslides in Residual Soils in Humid Tropical Environments [PDF]

, 2007
Landslide mechanisms and processes, particularly within the basal deformation region during failure, are poorly understood in the current knowledge.

Mechanisms of internal friction in soils and rocks

Geotecnia, 1972
Analisam-se os diferentes mecanismos que geram atrito interno de solos e rochas por efeito de fricção, de cunha, de rotação e de rolamento. A partir da cinemática desses mecanismos, relacionam-se os ngulos de atrito gerados com as formas das partículas dos solos ou dos blocos dos maciços rochosos e com a amplitude da distorção sofrida pelo terreno ...

The Cementation Mechanisms and Mechanical Properties of Different Soil–Rock Mixtures–Slurry Cements

Materials
This investigation focused on the cementation mechanisms and mechanical properties of soil–rock mixtures–slurry cement (SRM–SC) to ensure the safety of tunnels during operation. SRM–SC specimens were prepared with different types of slurry and rock contents based on an actual slurry injection ratio. The macroscopic level analysis involved measuring the

Performance assessment of a potential underground thermal storage facility: Case study of the closed mine Prosper‐Haniel in the Ruhr coal mining area in Germany

Deep Underground Science and Engineering, EarlyView.
This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

The investigation of tube sampling disturbance using transparent soil and particle image velocimetry [PDF]

A small-scale physical modelling system was developed and employed to investigate the effects of tube sampling. Amorphous silica and an oil blend of matching refractive index were mixed to form a transparent soil.

Carbon emission assessment of tunnel infrastructures: From construction to operation

Deep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

The role of frictional heating in the development of catastrophic landslides [PDF]

, 2009
In this work, a new thermo-mechanical model is developed by improving on an existing one, applicable to large deep seated landslides and rockslides consisting of a coherent mass sliding on a thin clayey layer.

Fluid‐induced slip on a rate‐and‐state fault during co‐ and post‐injection: The interplay of fluid pressure diffusion and poroelastic stress

Deep Underground Science and Engineering, EarlyView.
Fault slip can occur ahead of the injection pressure front due to poroelastic stress. Our model captures the interaction of pressure, stress, and friction, providing new insights into injection‐induced seismicity and post‐injection fault slip. Shut‐in operations can either mitigate or accelerate seismic events depending on fault conditions and ...
