Uchaneka oluPhezulu olungenamthungo oluKhanyayo
Iimoto, iinxalenye zoomatshini, njl.njl. zineemfuno eziphezulu ekuchanekeni nasekugqibeni kwemibhobho yentsimbi.Abasebenzisi bemibhobho yentsimbi echanekileyo ayingobasebenzisi kuphela abaneemfuno eziphezulu ezichanekileyo zokuchaneka kunye nokuguda.Ngenxa yokuba ukuchaneka kokuchaneka kwemibhobho eqaqambileyo kuphezulu kwaye ukunyamezela kunokugcinwa kwii-2--8 iingcingo, abaninzi abasebenzisi be-machining baya kusindisa abasebenzi, izinto eziphathekayo kunye nokulahlekelwa kwexesha.Iityhubhu zentsimbi ezingenamthungo okanye intsimbi engqukuva zitshintshwa kancinane zibe yimibhobho eqaqambileyo echanekileyo.
Nye:Ityhubhu eyaziwayo engenamthungo idayamitha yangaphandle, ukucaciswa, ubukhulu bodonga ukuze ikwazi ukuthwala indlela yokubala uxinzelelo (amandla okuqina ezinto ezahlukeneyo zemibhobho yentsimbi ahlukile)
Uxinzelelo = (ubukhulu bodonga * 2 * imathiriyeli yombhobho wentsimbi amandla okuqina) / (idayamitha yangaphandle * i-coefficient)
Eyesibini: Umbhobho owaziwayo ongenamthungo idayamitha yangaphandle yombhobho wentsimbi engenamthungo kunye nendlela yokubala ubukhulu bodonga phantsi koxinzelelo:
Ubukhulu bodonga = (uxinzelelo * idayamitha yangaphandle * i-coefficient) / (2 * imathiriyeli yombhobho wentsimbi ukomelela)
Ezintathu: Indlela yokubonakalisa i-coefficient yoxinzelelo lwetyhubhu ekhanyayo engenamthungo:
Uxinzelelo lombhobho wentsimbi P<7Mpa i-coefficient S=8
7
Uxinzelelo lombhobho wentsimbi P>17.5 i-coefficient S=4
