Offshore Bridge Detection in Polarimetric SAR Images Based on Water Network Construction Using Markov Tree

Remote Sensing, 2022
It is difficult to detect bridges in synthetic aperture radar (SAR) images due to the inherent speckle noise of SAR images, the interference generated by strong coastal scatterers, and the diversity of bridge and coastal terrain morphologies.

Energy Characteristics of Acoustic Emission at the Volume-Expansion Point of a Rock Bridge: A New Insight into the Evolutionary Mechanism of Coastal Cliff Collapse

Journal of Marine Science and Engineering, 2021
The recession of a coast can destabilize coastal cliffs. The stability of a cliff is controlled by a rock bridge. Identifying the volume-expansion point of rock bridges is crucial to assess cliff stability, but currently there are few identifying methods.

Solvent-regulated pore structure of NH2-MIL-125(Ti) and its CO2 capture performance in cement surface coatings

Journal of CO2 Utilization
This study prepared a series of NH2-MIL-125(Ti) samples (denoted as NMT-x%) by tuning the methanol fraction (20%, 30%, 40%, and 50%) in a mixed methanol/N,N-dimethylformamide (MeOH/DMF) solvent system, and investigated their pore structure and ...

Study on the Time-dependent Reliability of Corroded Reinforced Concrete Bridge Structures due to Ship Impact

Advances in Civil Engineering, 2022
The cumulative damage caused by chloride ion erosion to coastal bridge structures reduces the ship impact resistance of channel bridge structures and leads to changes in reliability of bridge structures on ship impact.

Dynamic performance of simply supported girder bridges subjected to successive earthquake-tsunami events

Advances in Bridge Engineering, 2022
Coastal bridges are susceptible to severe damage when subjected to successive earthquake-tsunami events. Previous studies mainly consider the tsunami loadings as hydrodynamic forces, whereas other hydrodynamic forces such as uplift and slamming forces ...

Numerical Investigation of Wave Force on Coastal Bridge Decks Close to a Sloping Seabed

Journal of Marine Science and Engineering
Large waves pose a significant threat to the safety of low-laying coastal bridges. In 2004 and 2005, many coastal bridges were destroyed by the large waves generated by Hurricane Ivan and Katrina.

Use of UHPC Jackets in Coastal Bridge Piles

Second International Interactive Symposium on UHPC, 2019
Concrete deteriorates for a variety of reasons, but corrosion of steel reinforcement has been one of the most prevalent mechanisms of deterioration since concrete structures were introduced in the early 1900s. It affects many types of concrete elements, especially the substructures of coastal bridges.

Seismic fragility analysis of coastal bridges considering different corrosion damage modes among multiple RC bridge columns

Case Studies in Construction Materials
In a typical coastal bridge structure, the multiple reinforced concrete (RC) bridge columns possess different distributions of the atmospheric, splash-tidal, and submerged zone along the elevation, owing to the seabed topography and depth difference ...
