Granite yog ib lub pob zeb igneous ntuj uas paub txog nws qhov ruaj khov thiab ruaj khov, ua rau nws yog cov khoom siv zoo tshaj plaws rau ntau yam kev siv, suav nrog kev tsim cov cuab yeej siv kho qhov muag. Lub neej ntev ntawm cov cuab yeej no yog qhov tseem ceeb rau cov kws tshawb fawb, cov kws tshawb fawb txog hnub qub, thiab cov kws tshaj lij uas vam khom qhov tseeb thiab qhov tseeb. Kev nkag siab txog yuav ua li cas cov khoom granite txuas lub neej ntawm cov cuab yeej kho qhov muag tuaj yeem ua rau pom qhov tseem ceeb ntawm kev xaiv cov khoom siv hauv kev tsim qauv thiab kev tsim khoom.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm granite yog nws qhov nyuaj tshwj xeeb. Cov cuab yeej no ua kom ntseeg tau tias cov khoom siv kho qhov muag, xws li cov mounts thiab cov hauv paus, tseem ruaj khov thiab siv tau ntev. Tsis zoo li cov ntaub ntawv mos dua, granite tsis yooj yim khawb lossis deform, uas yog qhov tseem ceeb rau kev tswj hwm qhov sib phim thiab kev ncaj ncees ntawm cov kab ke kho qhov muag. Qhov kev ruaj khov no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov siab, qhov twg txawm tias qhov me me tsis sib xws tuaj yeem ua rau muaj qhov yuam kev loj hauv kev ntsuas lossis kev soj ntsuam.
Tsis tas li ntawd xwb, granite muaj cov coefficient qis ntawm thermal expansion. Qhov no txhais tau tias nws tsis nthuav dav lossis cog lus ntau nrog kev hloov pauv kub, uas yog qhov tseem ceeb rau cov cuab yeej siv kho qhov muag uas yuav siv tau rau hauv ntau yam xwm txheej ib puag ncig. Los ntawm kev txo cov teebmeem ntawm kev hloov pauv thermal, cov khoom granite pab tswj kev calibration thiab kev ua tau zoo ntawm cov khoom siv kho qhov muag, kom ntseeg tau tias lawv tseem ntseeg tau rau lub sijhawm ntev dua.
Tsis tas li ntawd xwb, granite txoj kev tiv thaiv ntuj tsim rau cov dej noo thiab cov tshuaj lom neeg ua rau lub neej ntawm koj cov cuab yeej kho qhov muag ntev dua. Tsis zoo li cov hlau, uas tuaj yeem xeb lossis lwj hauv qab cov xwm txheej hnyav, granite tsis raug cuam tshuam, muab lub platform ruaj khov rau cov khoom siv kho qhov muag rhiab heev.
Tag nrho hauv txhua yam, kev siv cov khoom granite rau hauv cov cuab yeej siv kho qhov muag tuaj yeem ua rau lawv lub neej ntev dua. Qhov nyuaj ntawm cov khoom siv, qhov nthuav dav thermal tsawg, thiab kev tiv taus cov yam ntxwv ib puag ncig ua rau nws yog qhov kev xaiv zoo heev los xyuas kom meej tias cov cuab yeej no ruaj khov thiab ntseeg tau uas tseem ceeb rau kev tshawb nrhiav thiab kev tshawb pom.
