Thaum nws los txog rau kev tsim cov txheej txheem tswj kev txav mus los uas raug heev, kev xaiv cov ntaub ntawv ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov kev ua tau zoo ntawm lub kaw lus. Hauv cov xwm txheej ntawm cov theem ntsug, muaj ob qho kev xaiv ntawm cov ntaub ntawv: hlau thiab granite. Thaum hlau yog cov ntaub ntawv ib txwm siv rau cov ntawv thov no, granite tau tshwm sim ua lwm txoj hauv kev zoo heev hauv lub sijhawm tsis ntev los no. Hauv tsab xov xwm no, peb yuav tshawb nrhiav vim li cas granite feem ntau yog qhov kev xaiv zoo dua rau cov theem ntsug, thiab cov txiaj ntsig nws muab ntau dua li hlau.
1. Kev Ruaj Ntseg
Granite paub txog nws qhov ruaj khov thiab qhov tseeb ntawm qhov loj. Qhov no yog vim nws yog pob zeb ntuj uas tau tsim los ntau lab xyoo dhau los hauv qab kev nyuaj siab thiab cua sov. Cov txheej txheem ntuj no ua rau granite ntom dua thiab ruaj khov dua li cov khoom siv tib neeg ua, suav nrog hlau. Rau cov theem linear, kev ruaj khov thiab qhov tseeb yog qhov tseem ceeb, thiab granite ua tau zoo hauv cov cheeb tsam no, ua rau nws yog qhov kev xaiv zoo tshaj plaws.
2. Kev Rigidity Siab
Granite muaj qhov rigidity lossis stiffness index siab, uas yog qhov ntsuas ntawm cov khoom siv lub peev xwm los tiv taus kev khoov lossis deformation hauv qab load. Cov khoom no yog qhov tseem ceeb rau cov theem ntsug linear, uas yuav tsum tau rigid kom tswj tau qhov kev txav mus los kom raug. Granite qhov rigidity siab ua kom ntseeg tau tias cov theem no yuav tsis deform hauv qab load, uas ua rau lawv ntseeg tau dua thiab raug dua li lawv cov hlau counterparts.
3. Kev co zoo dua
Granite kuj paub txog nws cov yam ntxwv zoo heev uas ua rau nws tsis co. Cov yam ntxwv no ua rau nws zoo tagnrho rau cov ntawv thov uas muaj qhov chaw siab, qhov twg kev co tuaj yeem ua rau qhov tseeb ntawm qhov tso zis kawg tsis meej. Tsis zoo li hlau, granite muaj cov coefficient damping siab dua uas txo cov kev co ntau dhau, ua rau muaj kev raug thiab kev raug ntau dua.
4. Hnav Tsis Taus
Granite yog ib yam khoom siv uas tiv taus kev hnav ntau dua li hlau. Qhov no yog vim nws yog ib yam khoom siv tawv dua, uas txhais tau tias nws tuaj yeem tiv taus kev hnav thiab tsim kua muag ntau dua hauv nws lub neej yam tsis poob nws qhov tseeb thiab qhov tseeb. Yog li ntawd, theem granite linear tuaj yeem kav ntev dua li hlau, ua rau nws yog ib qho kev daws teeb meem pheej yig dua hauv lub sijhawm ntev.
5. Kev Txij Nkawm Yooj Yim
Lwm qhov zoo ntawm granite yog tias nws tsis tas yuav tsum tau saib xyuas ntau npaum li hlau. Granite tsis xeb lossis lwj, thiab nws tiv taus cov tshuaj lom neeg thiab lwm yam tshuaj lom neeg. Yog li ntawd, nws tsis tas yuav tsum tau saib xyuas tas li thiab tuaj yeem kav ntev ntau xyoo yam tsis muaj nqi kho ntau.
Xaus lus
Xaus lus, muaj ntau yam zoo ntawm kev siv granite dua li hlau rau cov theem ntsug. Granite muaj kev ruaj khov dua, kev ruaj khov, kev co, kev tiv thaiv kev hnav, thiab xav tau kev saib xyuas me ntsis. Cov yam ntxwv no ua rau granite yog qhov kev xaiv zoo dua rau cov ntawv thov siab uas qhov tseeb thiab kev ntseeg siab yog qhov tseem ceeb.
