Experimental Study of Dynamic Response of Seismic and Isolated Continuous Girder Bridge Under Earthquake

工程科学与技术, 2015
:Aimed to investigate the seismic and isolated performance of one pure continuous girder bridge across ocean,the seismic and isolated experimental model with the scale of 1∶10 was designed and made by simplifying continuous girder bridge as single pier ...

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.

Energy evolution‐based damage quantification and failure prediction of fault zone tunnel lining concrete: A novel acoustic emission–strain energy coupling approach

Deep Underground Science and Engineering, EarlyView.
This study investigates the damage evolution and failure mechanisms of tunnel lining concrete in active fault zones through uniaxial compression tests integrated with acoustic emission (AE) monitoring. A strong linear correlation is identified between the AE cumulative absolute energy and the total strain energy, providing a reliable energy‐based ...

Analysis of lining force transmission coefficient and surrounding rock displacement in lined rock caverns for underground gas storage

Deep Underground Science and Engineering, EarlyView.
This study derives an explicit expression for the lining force transmission coefficient of underground gas storage lined rock caverns (LRCs) via the complex variable function method, considering the displacement release coefficient. Taking the 1‰ tensile strain of surrounding rock as the criterion to determine lining thickness, it systematically ...

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 ...

Renewable energy mapping in Northeastern Morocco: A geographic information system‐based comparison of geothermal, solar, and wind potential in the Guercif‐Guilliz and Beni Snassen regions

Deep Underground Science and Engineering, EarlyView.
The graphical abstract summarizes a geographic information system (GIS)‐based synthesis of renewable energy resources in Northeastern Morocco, focusing on the Guercif‐Guilliz and Beni Snassen areas. It visually presents the spatial distribution of solar irradiation and wind energy potential derived from available datasets, alongside their relationship ...
