Kev tshuaj xyuas kev ruaj khov thiab kev ruaj khov ntawm cov granite puag.

 

Granite, ib lub pob zeb ntuj uas siv dav dav, yog lub pob zeb uas muaj npe nrov rau nws qhov ruaj khov thiab ruaj khov, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv hauv kev tsim kho. Kev tshuaj xyuas qhov ruaj khov thiab ruaj khov ntawm cov pob zeb granite yog qhov tseem ceeb hauv kev nkag siab txog lawv cov kev ua tau zoo hauv qab ntau yam xwm txheej ib puag ncig thiab cov khoom thauj.

Granite yog pob zeb igneous uas muaj quartz, feldspar, thiab mica, uas ua rau nws muaj zog thiab tiv taus huab cua. Thaum tshuaj xyuas qhov ruaj khov ntawm cov hauv paus granite, ntau yam tseem ceeb los ua si, suav nrog cov khoom siv hauv av, porosity, thiab qhov muaj cov kab nrib pleb lossis tawg. Cov yam ntxwv no txiav txim siab seb granite tuaj yeem tiv taus cov txheej txheem huab cua thiab tshuaj lom neeg zoo li cas, xws li cov voj voog khov-thaw, nag acid, thiab kev puas tsuaj.

Kev tshuaj xyuas kev ruaj khov tsom mus rau lub peev xwm ntawm granite los tswj nws cov qauv kev ruaj khov hauv qab ntau yam kev thauj khoom, suav nrog cov zog static thiab dynamic. Qhov no tseem ceeb heev rau cov ntawv thov xws li kev tsim kho txoj kev, qhov twg granite bases ua haujlwm ua cov txheej txheem hauv paus. Cov engineers feem ntau ua qhov kev ntsuam xyuas los ntsuas lub zog compressive, shear strength, thiab modulus ntawm elasticity ntawm granite, kom ntseeg tau tias nws tuaj yeem txhawb nqa qhov hnyav ntawm cov tsheb thiab tiv taus deformation dhau sijhawm.

Tsis tas li ntawd xwb, yuav tsum xav txog qhov cuam tshuam rau ib puag ncig ntawm cov pob zeb granite. Tej yam xws li qhov kub thiab txias hloov pauv, cov dej noo noo, thiab kev raug tshuaj lom neeg tuaj yeem cuam tshuam rau kev ua haujlwm ntev ntawm granite. Kev saib xyuas thiab kev saib xyuas tsis tu ncua tuaj yeem pab txo cov teeb meem uas yuav tshwm sim, ua kom ntseeg tau tias cov pob zeb granite tseem ruaj khov thiab siv tau ntev thoob plaws lawv lub neej.

Xaus lus, qhov kev tshuaj xyuas qhov ruaj khov thiab kev ruaj khov ntawm cov hauv paus granite yog qhov tseem ceeb rau kev ua kom lawv ua haujlwm tau zoo hauv cov haujlwm tsim kho. Los ntawm kev nkag siab txog cov yam ntxwv ntawm granite thiab cov yam ntxwv uas cuam tshuam rau nws cov kev ua tau zoo, cov engineers tuaj yeem txiav txim siab tau zoo uas ua rau lub neej ntev thiab kev ntseeg siab ntawm cov qauv tsim los ntawm cov hauv paus granite.
