Seismic shear strength of thin-walled circular hollow RC bridge piers considering flexural-shear interaction

The thin-walled circular hollow reinforced concrete (RC) bridge piers provide favorable material efficiency, but their seismic shear strength is difficult to evaluate because hollow-section geometry and post-yield flexural damage can jointly reduce the available shear-transfer ca...

High-resolution land cover mapping from coarse labels via a noisy label learning-guided cross-scale framework

High-resolution remote sensing images (HRSIs) provide essential data support for land cover mapping, where deep learning has shown great promise. However, deep learning-based methods rely on abundant high-quality annotations, while low-resolution coarse labels are difficult to us...

GNSS monitoring and stability evolution mechanism of the S-J1 deformation body in the lower reaches of the Jinsha River

Catastrophic landslides triggered by reservoir impoundment represent one of the most destructive geohazards in the field of hydropower engineering, posing significant threats to human lives, property, and the long-term operational safety of critical infrastructure. A large hydrop...

Electrical conductivity models for bubble-bearing marine fine-grained sediments

Abstract Large sediment-displacing bubbles are widespread in seafloors and typically found in shallow and fine-grained sediments. These bubbles have significant environmental and engineering impacts. Acoustic methods are the most widely used geophysical investigation method for b...
