Cov Qauv Qauv
- Steel Box Girder Bridges: Zoo heev cua tsis kam thiab siab tag nrho rigidity; ib txwm siv rau ntev -ntev hiav txwv- hla choj.
- Steel Truss Choj: Lub teeb yuag thiab muaj zog spanning peev xwm; siv rau qhov sib sib zog nqus- dej los yog cov xwm txheej uas yuav tsum tau txo qis hauv paus loj.
- Cable-Txoj kev nyob ruaj (Steel Main Girder): Muaj peev xwm nthuav dav thiab tsim kom zoo nkauj; ib qho ntawm cov qauv tseem ceeb ntawm hiav txwv- hla choj.
- Suspension Choj (Steel Box Girder / Steel Truss Stiffening Girder): Ntau tshaj qhov muaj peev xwm; haum rau strait - tej yaam num.
Khoom zoo
- Loj span: Lub marine ib puag ncig txhais tau hais tias hla - hiav txwv steel txuas hniav feem ntau yuav tsum tau loj los yog super- loj span lug.
- Ib puag ncig hnyav: Lawv yuav tsum tiv taus cua txias, siab ntsev tsuag corrosion, nthwv dej loj, dej hiav txwv, av qeeg, thiab lwm yam ntuj tsim.
- Kev tsim kho siab nyuaj: Lub hauv paus yog qhov nyuaj rau kev tsim, ua rau kev tsim kho nyuaj.
- Cov kev cai kav ntev: Cov qauv hlau muaj qhov cuam tshuam rau corrosion, yog li yuav tsum muaj kev tiv thaiv -corrosion systems (xws li, hnyav-cov dej num tiv thaiv-corrosion coatings, anti-corrosion steel, thiab cathodic tiv thaiv).
- Environmental tej yam kev mob: Marine corrosion, typhoons, nthwv dej, tides; dej tshiab corrosion, dej nyab, tam sim no velocities.
Qhov sib txawv tseem ceeb ntawm tus ntoo khaub lig- hiav txwv steel choj thiab hla- tus choj hla dej

Daim ntawv thov Scenario
- Txuas cov nroog ntug hiav txwv thiab cov Islands tuaj;
- Hla bays, estuaries, thiab straits;
- Txoj kev loj thiab kev tsheb ciav hlau hla- hiav txwv hla;
- Cov dej num hauv hiav txwv xav tau kev tsim kho sai lossis txo lub hauv paus loj.
Yog tias koj xav tau cov ntaub ntawv ntau ntxiv txog lub hiav txwv hla steel choj los yog xav tau ib qho kev tsocai, thov koj xav tiv tauj kuv. Kuv yuav muab kev pabcuam tshaj lij rau koj!
