Qhov project no yog ib lub voj voog ib puag ncig kev lag luam qhov chaw ncej / qhov siab yog 51 meters / tag nrho ntev 688 meters / tag nrho ncua 46 meters
Lub khoos phis tawj program tau tsim tus kheej qhov hnyav ntawm steel qhov chaw ncej;
Lub load yuav tsum ua ntawm cov nodes, thiab cov tswvcuab tsis dais lateral loads;
Lub thav duab yuav tsum nruj me ntsis raws li kev lag luam tus qauv "qhov chaw ncej pob qij txha pob qij txha" JG / T10-2009
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 daim phiaj thav duab yog cia li superimposed nyob rau hauv lub internal force 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.
