(1) Kev thauj khoom
Raws li kev txhim kho kev loj thiab kev tsim kho kev tsim kho tawm los ntawm Ministry of TSHEB THAUJ MUS LOS, lub load coefficient yog raws li nram qab no:
Lub tshaj tawm coefficient ntawm nthuav hom kev nthuav dav thiab lwm yam thaum lub thawv girder qhob yog poured: 1.05;
Dynamic Coefficient ntawm nchuav Qhob: 1.2
Kev sib cuam tshuam ntawm daim foos neeg taug kev mus nrog tsis muaj thauj: 1.3;
Kev ruaj khov coefficient ntawm kev tsis kam mus ntxeev thaum pouring pob zeb ua thiab daim ntawv traveler: 2.0;
Qhov kev nyab xeeb rau kev siv ib txwm siv ntawm daim foos Traveler yog 1.2.
(2) thauj khoom ntawm lub ntsiab truss ntawm daim foos traveler
Lub thawv Girder Luv: box girder thauj mus rau cov kev suav ntau ntau, qhov hnyav yog 411.3 tons.
Cov cuab yeej siv siv thiab cov neeg ntseeg neeg thauj khoom: 2.5kPA;
Thauj khoom los ntawm kev pov tseg thiab vibrating ntawm cov pob zeb ua: 4kpa;
(3) Kev sib xyaw ua ke
Kev thauj khoom ua ke ntawm cov tawv nqaij thiab lub zog checking: qhob tsheb ciav hlau + Kev tsim khoom lag luam: Qhov hnyav ntawm daim foos (0.3 * Qhov hnyav ntawm daim foos Traveler) + Tus Cua thauj khoom.
Xa mus rau cov lus qhia tshwj xeeb rau kev tsim kho cov choj tsheb loj thiab cov Culverts Cov Cai:
(1) Qhov hnyav tswj ntawm daim foos Traveler yog ntawm 0.3 thiab 0.5 zaug ntawm cov qhob qhov hnyav ntawm th nchuav.
(2) Qhov nyiaj pub tshaj plaws uas tau tso cai deformation (suav nrog cov lej ntawm sling deformation): 20mm
(3) qhov kev nyab xeeb ntawm anti ntxeev thaum lub sij hawm tsim kho lossis txav: 2.5
(4) qhov kev nyab xeeb ntawm tus kheej Anchored System: 2
