1. Raucev nrog rau siab ncov shaving yuav tsum, vim tsis muaj roj noj los ntawm cov neeg siv, nquag cov yeeb nkab siab hloov pauv, thiab alternating stresses raug kev txom nyem los ntawm steel kav, qhov tsis xws luag nyob rau hauv cov kav dej yuav nthuav nyob rau hauv lub alternating stresses.Kauv welded steel kav nrog ntau welds thiab qhov ua tau zoo ntawm qhov tsis xws luag tsis tuaj yeem lav lawv cov haujlwm ib txwm muaj.

2. Lub raj xa dej hla ntawm thaj tsam seismic txhaum cai lossis dhau ntawm thaj chaw av qeeg loj hauv zos.Vim muaj kev ua geological nquag nyob rau hauv cov ntu no, qhov ntev los yog axial alternating stresses tuaj yeem tsim tawm ntawm cov raj xa dej.Muaj ntau cov kauv welds, thiab qhov muaj peev xwm ntawm qhov tsis xws luag yog siab dua li ntawm submerged arc welded steel kav.Nyob rau hauv lub sij hawm ntev kev ntxhov siab, qhov tshwm sim ntawm cov xwm txheej nyob rau hauv kauv welded steel kav yog ntau dua li ntawm submerged arc welded steel kav.Yog li ntawd, submerged arc steel kav yuav tsum tau siv nyob rau hauv cheeb tsam no.

3. Rau cov kav dej uas muaj siab sab hauv thiab sab nrauv los tiv thaiv corrosive txheej, yuav tsum siv cov kav dej submerged arc steel.Kauv submerged arc welded steel kav muaj ntau welds, thiab weld seam qhov siab yog feem ntau siab dua li ntawm submerged arc welded steel kav.Thaum cov yeeb nkab steel tiv thaiv los ntawm sab hauv thiab sab nraud corrosion, kev sib xyaw ntawm cov khoom siv los tiv thaiv corrosive thiab cov yeeb nkab liab qab tsis muaj zog npaum li cov yeeb nkab hauv qab arc welded steel yeeb nkab, thiab cov nyhuv anti-corrosive yuav tsis submerged.

4. Rau qhov tseem ceeb ntawm kev tsim hluav taws xob, cov kav dej submerged arc steel yuav tsum tau siv.Txij li kev txij nkawm thiab kev tswj hwm yav tom ntej yuav nyuaj dua li cov kav dej zoo tib yam, kev siv cov kav dej arc steel nrog kev ua tau zoo yog qhov tseem ceeb tshwj xeeb.

1. Rau kev sib txuas tsis muaj zog hauv cov kav dej, xws li cov kav dej kub hauv lub luj tshib, cov kav dej arc steel yuav tsum tau siv.Vim qhov kev hloov pauv ntawm kev taw qhia, lub luj tshib kub-dov tuaj yeem tiv taus ntau dua sab hauv thiab sab nraud ntau dua li cov yeeb nkab ncaj nraim ntawm cov kav dej ib txwm muaj.Vim muaj ntau yam hauv cov txheej txheem kev txwv, nws txoj kev ntxhov siab tsis yooj yim tshem tawm, thiab nws yog ib qho kev sib txuas tsis muaj zog hauv cov kav dej ntev.Kev siv cov submerged arc welded steel kav nrog cov khoom zoo tuaj yeem ua rau cov kev tsis txaus no.
