Hauv kev tsim kho cov nroj tsuag, tib neeg feem ntau xaiv cov qauv hlau. Vim yog kev tsim kho ceev ceev ntawm steel qauv Rhiav, cov qauv steel muaj zog heev thiab ruaj khov. Qhov tseem ceeb tshaj plaws yog qhov chaw tsim steel qauv yog hloov tau, uas yog qhov tsim nyog rau kev cob qhia kev lag luam thiab kev cob qhia ntau lawm. Txawm li cas los xij, teeb meem yuav tshwm sim hauv kev siv cov txheej txheem steel, xws li tawg thiab corrosion ntawm steel qauv pob qij txha, loosening ntawm bolted pob qij txha thiab lwm yam. Cov teeb meem no zoo li me me, tab sis lawv ua rau muaj kev hem thawj rau tag nrho kev nyab xeeb ntawm steel qauv nroj tsuag. Yog li ntawd, kev soj ntsuam kev nyab xeeb ntawm cov qauv steel yuav tsum tau ua ua ntej kev tsim khoom thiab tom qab muaj teeb meem tshwm sim.
I. Steel qauv tshuaj xyuas thiab kev soj ntsuam cov ntsiab lus.
Kev tshawb nrhiav thiab kev ntsuam xyuas ntawm cov qauv steel feem ntau suav nrog cov qauv steel nrog cov kev xav tau tshwj xeeb xws li cov khoom siv, cov khoom siv, kev sib txuas thiab ntawm qhov tsis xws luag, cov txheej txheem, kev puas tsuaj thiab kev nyab xeeb, kev siv tau, durability thiab seismic Performance appraisal, xws li steel qauv tom qab hluav taws, qaug zog nrhiav pom. thiab kev ntsuam xyuas ntawm cov qauv steel, dynamic nrhiav thiab ntsuam xyuas cov qauv steel, thiab lwm yam.
II. Cov ntsiab lus ua haujlwm yooj yim ntawm -kev tshuaj xyuas qhov chaw.
1. Sau cov ntawv qhia txog engineering geological daim ntawv ntsuam xyuas, tsim cov duab kos, suav, tsim kev hloov pauv, cov ntaub ntawv soj ntsuam kev sib hais haum, cov ntaub ntawv tsim kho, cov ntaub ntawv pov thawj, cov ntaub ntawv tshuaj xyuas cov khoom, raws li cov duab kos, cov ntaub ntawv lees paub tiav thiab lwm yam ntaub ntawv cuam tshuam;
2. Nkag siab txog kev tsim kho, kev siv, kev puas tsuaj thiab kho keeb kwm ntawm lub tsev, xws li kev tsim kho, kev hloov pauv, kev tu, kev siv hloov, kev siv cov xwm txheej thiab kev siv ib puag ncig kev hloov ntawm lub tsev, thiab seb puas muaj kev puas tsuaj tshwm sim;
3. Kev tshawb nrhiav qhov chaw thiab kev txheeb xyuas cov ntaub ntawv. Thaum muaj cov duab kos, ntawm - qhov chaw pov thawj yuav tsum tau ua; Yog tias tsis muaj daim duab kos duab, daim duab kos duab yuav tsum tau kos raws li qhov tseeb ntawm cov qauv;
4. Kev tshawb nrhiav yooj yim. Kev tshawb nrhiav ntawm kev pabcuam ib puag ncig ntawm steel qauv. Cov khoom siv ntsuas kev ua haujlwm. Node kev sib txuas xwm txheej kuaj. Kev kuaj kev puas tsuaj. Kev kuaj tus qauv deformation. Yog tias tsim nyog, qhov kev xeem dynamic structural thiab field load test ntawm cov qauv lossis cov khoom tuaj yeem ua tiav.
