(1) Load factor
Raws li txoj kev loj choj tsim thiab kev tsim kho specification tawm los ntawm Ministry of Transportation, lub load coefficient yog raws li nram no:
Lub overload coefficient ntawm expansion hom thiab lwm yam thaum lub thawv girder pob zeb yog poured: 1.05;
Dynamic coefficient ntawm pouring qhob: 1.2
Qhov cuam tshuam ntawm Daim Ntawv Mus Los Tsiv nrog tsis muaj kev thauj khoom: 1.3;
Stability coefficient ntawm kev tiv thaiv overturning thaum pouring qhob thiab daim ntawv Traveler: 2.0;
Qhov zoo tshaj plaws kev nyab xeeb rau kev siv ib txwm siv daim ntawv Traveler yog 1.2.
(2) Thauj khoom rau ntawm lub ntsiab truss ntawm Daim Ntawv Mus Ncig
Lub Thawv girder load: Lub thawv girder load coj qhov kev suav loj tshaj plaws, qhov hnyav yog 411.3 tons.
Cov khoom siv tsim kho thiab cov neeg coob coob load: 2.5kPa;
Load tshwm sim los ntawm dumping thiab vibrating ntawm pob zeb: 4kpa;
(3) Load ua ke
Kev sib xyaw ua ke ntawm kev nruj thiab kev kuaj xyuas lub zog: pob zeb hnyav + Daim Ntawv Cov Neeg Ncig Qhov hnyav + cov khoom siv tsim khoom + cov neeg coob coob + kev vibration quab yuam thaum lub pob tawb txav: qhov hnyav ntawm daim ntawv Traveler + qhov cuam tshuam load (0.3 * qhov hnyav ntawm daim ntawv Traveler) + cua load.
Xa mus rau kev qhia tshwj xeeb rau kev tsim kho cov choj loj thiab cov kev cai culverts:
(1) Kev tswj qhov hnyav ntawm Daim Ntawv Mus Ncig yog nyob nruab nrab ntawm 0.3 thiab 0.5 npaug ntawm cov pob zeb hnyav ntawm th pouring qhob.
(2) Qhov siab tshaj plaws deformation (nrog rau qhov sib npaug ntawm sling deformation): 20mm
(3) Kev nyab xeeb ntawm kev tiv thaiv overturning thaum lub sij hawm tsim kho lossis tsiv: 2.5
(4) Kev nyab xeeb ntawm tus kheej anchored system: 2
