Description
How do massive bridges rise directly out of open water? 🌉🌊
Building deep-water crossings requires heavy-duty marine geotechnical engineering from the seabed up:
Driven Pile Foundations: Heavy steel or reinforced concrete piles are driven deep into the seabed until they hit load-bearing bedrock or stable soil.
Underwater Pile Caps: Massive reinforced concrete slabs are cast over the pile clusters to tie them together, creating a unified base to distribute extreme vertical and lateral loads.
Pier Columns & Rebar Cages: Dense steel reinforcement cages are tied in stages on rising scaffolding, then encased in formwork and high-strength concrete to form the main superstructure supports.
Double-Deck System: Multi-tiered deck structures maximize corridor capacity—carrying highway traffic and high-speed rail simultaneously across the same marine footprint.
Engineering beneath the surface makes the structure above possible.
