Numerical research on anti‐dislocation measures design of deep‐buried tunnels in an anisotropic rock mass area

Deep Underground Science and Engineering, EarlyView.
This paper conducts a numerical simulation study on the construction of a deep‐buried tunnel in an anisotropic stratum area. A statistical analysis of the effects of two anti‐faulting design measures, namely, a conventional design and an articulated design, is carried out, and the results demonstrate the effectiveness of the anti‐faulting structures ...

Analysis of crack development in loess deep filled ground based on physical modelling tests

Zhongguo dizhi zaihai yu fangzhi xuebao
Cracks are a common issue in deep filled construction projects, and conventional methods often struggle to accurately predict their development. To guide the anti-crack design for deep-filled loess projects, a prototype of a typical gully section from a ...

Probabilistic characterization of seepage‐induced tunnel face failure via a two‐phase double‐point material point method

Deep Underground Science and Engineering, EarlyView.
To address seepage‐induced tunnel face collapse, this study develops a two‐phase double‐point MPM framework to capture large‐deformation hydro‐mechanical interactions. Incorporating a cementation‐based constitutive model with dynamic permeability updates, the model is successfully validated against saturated granular‐column collapse experiments ...

Centrifuge modelling of monotonic and cyclic lateral responses of monopiles in quartz and carbonate sands [PDF]

E3S Web of Conferences
This study evaluates the soil-structure interaction of monopiles subjected to monotonic and cyclic lateral loading by means of centrifuge modelling. The monopile were installed in two types of dense sands: quarts and carbonate. To evaluate the static and

Investigation on the mechanical behavior of the multiple‐layered lining structure of a water conveyance tunnel with high internal water pressure

Deep Underground Science and Engineering, EarlyView.
This study presents large‐scale similarity model testing (geometric ratio 3.6) of an innovative multiple‐layered lining system—comprising exterior precast segments, middle self‐compacting concrete, and an interior steel pipe—for high‐pressure (0.75 MPa) water conveyance tunnels.

Reusing depleted oil and gas wells for geothermal energy: Feasibility, challenges, and a decision‐making framework for sustainable conversion

Deep Underground Science and Engineering, EarlyView.
The graphical abstract presents a structured decision‐support framework for assessing the feasibility of converting depleted oil and gas wells into geothermal energy systems. The left panel illustrates a comprehensive, multi‐stage decision‐making framework progressing from prefeasibility screening and technical–economic analysis to policy alignment ...

An investigation of the arching mechanism in a geotechnical centrifuge

, 2021
Plane strain physical models of a piled embankment were investigated in a geotechnical centrifuge at up to 110 times earth’s gravity (g). The test series had constant pile geometry, but different embankments heights to better understand the deformational response of these systems.
