Screening for long-span bridges.
Pylon and anchorage settlement together with splash-zone chloride ingress, in one view per bridge.
Why it matters
Sea bridges age at the waterline and settle at the foundations.
Cable-stayed and suspension bridges over the sea face chloride in the splash zone and settlement at pylons and anchorages. PILLAR screens both, and gives concession companies and owners periodic reporting material.
- Screen 5 mm/yr and 1/500 for long-span bridges
- Pylon and anchorage settlement per 80 m cell
- Chloride ingress and remaining years to cover cracking (p10/p50/p90)
- Periodic reporting material for concession companies
What PILLAR checks
Long-span bridges
Example (demo)
Incheon Bridge main span: SHI 81, grade B, chloride governing (97%).
Remaining life
Median 33 years to cover cracking in the demo model run.
Next check
Focus the next routine inspection on the top two drivers.
FAQ
Frequently asked questions
Can PILLAR see a bridge deck move?
InSAR measures movement of reflective surfaces such as decks, pylons and approaches. Moving traffic and water can reduce reliability; PILLAR marks such cells as uncertain.
Who uses the bridge report?
Owners and concession companies use it as internal screening material for periodic reporting and inspection planning.
