Cov yam ntxwv ntawm pob zeb ua lub tshuab thaiv.
Cov khoom siv masonry tshuab siv kaw kev siv thauj mus los kom nruj tswj kev ntim ib nrab ntawm cov khoom siv me me, kom ntseeg tau tias lub zog ntawm cov khoom los ntawm kev tiv thaiv cov liquefaction ntawm pob zeb cuam tshuam los ntawm aftershocks.
Qhov tshwj xeeb txiav thiab koov-tawg ntaus ntawv ua rau cov khoom xa mus rau hauv lub thawv pwm sai thiab nrawm; qhov tshwj xeeb ob-kawg hluavtaws tso zis tawm kev co tshuab thiab tsim kev tsim vibrator ua rau lub zog ua kom zoo siab tusyees faib rau hauv lub rooj tuav co.
Yog li txhawm rau txhawm rau paub tseeb tias qhov hnyav thiab lub zog ntawm cov khoom.
Cov qauv tag nrho ntawm cov tshuab masonry yog cov khoom siv me me, cov khoom siv yog qhov tsim nyog, thiab qhov kev sib hloov tau txais cov khoom siv kho tshuab, uas yog qhov tseeb thiab ntseeg tau.
Txo qhov kev siv dag zog thiab txhim kho kev ua tau zoo.
Txog nce thiab nqis siab, kev taw qhia kev vibration, zaus hloov kho lub nrig kom ua tiav qhov siab ntom nti, siab zog ua tiav molding nyhuv.
Ib lub tshuab yog ntau lub hom phiaj, thiab cov pwm sib txawv tuaj yeem siv los ua cov khoom thaiv ntawm cov duab sib txawv thiab cov ntsiab lus tshwj xeeb.
Cov cuab yeej qog ntawm txhua ntu yog yooj yim los saib, kev khiav lag luam yog yooj yim, kev saib xyuas yog yooj yim, thiab nws tsis nquag los ua tsis tiav los ua kom muaj kev ua haujlwm zoo ib yam.
