Impact of Coastal Infrastructure on Ocean Colour Remote Sensing: A Case Study in Jiaozhou Bay, China

open access: yesRemote Sensing, 2019
Spatial and temporal ocean colour data are increasingly accessible through remote sensing, which is a key tool for evaluating coastal biogeochemical and physical processes, and for monitoring water quality.

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

open access: yesRemote 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

open access: yesJournal 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.

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

open access: yesAdvances 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.

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

open access: yesJournal 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 ...

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

open access: yesAdvances 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 ...

Use of UHPC Jackets in Coastal Bridge Piles

open access: yesSecond 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.

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

open access: yesJournal 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.
