Sea locks that connect inland canals and rivers to the open sea are crucial links ensure efficient navigation of ships. Floating bollards (FBs) significant components locks, they affected by factors such as large ships, speed entry, irregular mooring lines coupled with corrosion chloride salts from seawater intrusion environment. These aggravate damage metal structures, which seriously threatens safety FBs. Overloading FBs forces caused illegal use for braking ships enter at excessive is...
Due to the harsh marine environment of chloride ion invasion and corrosion, issues long-term transport durability life evaluation for infrastructures constructed/maintained by recycled aggregate concrete (RAC) after enhancement remain poorly understood. For our studies, an accelerated carbonation modification method coarse (RCA) was adopted prepare carbonated (CRCA) samples, macroproperties, i.e., apparent density water absorption, CRCA were enhanced approximately 1.40-3.97% 16.3-21.8%,...
Due to the large scale of navigation ships, fast speed entering lock, and irregular mooring complicated flow conditions in lock chamber, it is common for floating bollards suffer structural damage or even failure due overloaded force. However, traditional cable load measurement method cannot offer real-time feedback on force characteristics bollards, making difficult accurately judge its service status. To this end, according bollard structure type condition a representative ship project...
Due to the sea water intrusion and development trend of using large-scale ships, more stringent requirements are put forward for safety delivery process mooring equipment operation shiplock. The maximum loads shiplock, i.e., floating column (FMC), generally occurred at end delivery. superimposed effect turbulent flow marine corrosive environment can accelerate failure structure which leads incidents, including structural damage FMC breakage lines ship, etc. is mostly influenced by three...
Column-pontoon type very large floating structure (CP-VLFS) operated at the deep and sea faraway areas are generally exposed to extremely complex wave conditions. The connectors of CP-VLFS subjected complicated hydrodynamic constraint loads when modules stimulated by long-tern forces. general method for analyzing performances marine structures their components is almost on basis potential flow/fluid theory (PFT), but its algorithm principle relatively would consume plenty computing time....
The utilization of waste concrete can not only effectively reduce carbon emissions but also facilitate resource conservation, intensification and recycling by producing recycled aggregate (RA) to further prepare (RAC). Nevertheless, the popularization application RA its RAC in coastal engineering are seriously restricted due insufficiency self-properties for as well durability issues, including influence long-term chloride ion invasion, reinforced (RC) structures built using exposed marine...
