Kuti mupeze mphamvu yodalirika komanso yayikulu yomangirira, ndikofunikira kuwonetsetsa kuti mphete yokhazikika pa nalimata ikukulirakulira.Ndipo cholepheretsa chokulitsa sichiyenera kugwa pa ndodo kapena kupindika kapena kupunduka mu dzenje.
Miyezo yamphamvu yamphamvu yokhazikika imayesedwa pansi pa mphamvu ya simenti ya 260 ~ 300 kgs / cm2, ndipo mtengo wokwanira wachitetezo suyenera kupitilira 25% ya mtengo wake.
