Qhov project no yog arched qhov chaw ncej / qhov siab yog 49 meters / tag nrho ntev 633 meters / tag nrho ncua 76.3 meters.

Qhov project no txais yuav steel qhov chaw thav duab, daim ntawv txhawb nqa yog lub hauv qab chord kev txhawb nqa, bolt pob sib koom, thiab ob txheej txheej zoo quadrangular pyramid daim phiaj dav hlau.Daim phiaj thav duab tau txais kev txhawb nqa ntawm cov pob zeb pob zeb ntawm ob sab, thiab cov kev txhawb nqa yog hinged nrog lub taub hau ntawm cov pob zeb.Cov vuam electrodes thiab cov xov hlau siv rau vuam yuav tsum ua tau raws li cov kev cai ntawm lub teb chaws tam sim no cov qauv.Cov vuam ntawm Q235B steels txais E43 series electrodes, thiab vuam ntawm Q345B steels txais E50 series electrodes.
Qhov chaw steel yog xam thiab tsim los ntawm MST2020 software.
Ntxiv nrog rau kev ua kom tau raws li cov cai ntawm lub teb chaws cov khoom siv, cov hlau siv hauv qhov project no yuav tsum tau ua raws li cov cai hauv qab no:
a) Qhov piv ntawm qhov ntsuas tus nqi ntawm lub zog tawm los ntawm cov hlau rau qhov ntsuas tus nqi ntawm lub zog tensile yuav tsum tsis txhob ntau tshaj 0.85;
b) Cov hlau yuav tsum muaj cov kauj ruam pom tseeb, thiab qhov elongation yuav tsum ntau dua 20%;
c) Cov hlau yuav tsum muaj qhov zoo weldability thiab tsim nyog cuam tshuam toughness;
Lub steel qhov chaw thav duab tsim siv 3D3S (version 14.0) software tsim ntawm cov yeeb nkab qauv siv computer-pab tsim thiab kev tsim cov txheej txheem los ua kom tiav cov kev ntsuam xyuas sab hauv ntawm cov tswv cuab thiab tsis siv neeg tsim ntawm tag nrho cov kev ntxhov siab ntawm microcomputer, thiab tus kheej- hnyav load ntawm steel qhov chaw ncej yog cia li superimposed nyob rau hauv lub internal zog tsom xam.
Qhov ntsuas qhov ntev ntawm tus pas nrig yog L0 = L, thiab qhov sib piv ntawm cov pas nrig tseem ceeb yog khi pas nrig ≤ 200 thiab compression pas nrig ≤ 150. Qhov sib luag ntawm lwm cov pas nrig yog khi pas nrig ≤ 250, siab pas nrig ≤ 180.
