Simbi yekuvaka ngarava kazhinji inoreva simbi yezvivakwa zvehull, izvo zvinoreva simbi inoshandiswa kugadzira hull zvivakwa zvinogadzirwa zvinoenderana nezvinodiwa zvechikamu chemagariro ekuvaka maratidziro. Inowanzorongedzerwa, yakarongwa uye inotengeswa sesimbi yakakosha. Ngarava imwe inosanganisira mahwendefa engarava, simbi yakaumbwa, nezvimwe.
Parizvino, makambani makuru makuru esimbi munyika yangu ane kugadzirwa, uye anogona kugadzira zvigadzirwa zvesimbi zvemugungwa zvinoenderana nezvinodiwa nevashandisi munyika dzakasiyana, dzakadai seUnited States, Norway, Japan, Germany, France, nezvimwewo.

Simbi yezvivakwa zvehull yakakamurwa kuita nhanho dzesimba zvichienderana neayo kushoma goho poindi: general simba remuumbirwo simbi uye yakakwirira simba structural simbi.
Iyo yakajairika simba yemaitiro simbi inotsanangurwa neChina Classification Society yakakamurwa kuita mana emhando nhanho: A, B, D, uye E; iyo yakakwirira-yakasimba simbi yesimbi inotsanangurwa neChina Classification Society yakakamurwa kuita matatu esimba nhanho uye mana emhando yepamusoro:

(3) Chengetedzo yekuendesa uye kugamuchirwa kwezvigadzirwa zvesimbi zvemugungwa:
1. Wongororo yemhando chitupa:
Iyo fekitori yesimbi inofanirwa kuendesa zvinhu zvinoenderana nezvinodiwa nemushandisi uye zvakatemerwa zvakabvumiranwa muchibvumirano uye nekupa chepakutanga chemhando chitupa. Chitupa chinofanira kunge chine zvinotevera zviri mukati:
(1) Zvinodiwa Specification;
(2) Nhamba yerekodhi yemhando uye nhamba yechitupa;
(3) Bira batch nhamba, tekinoroji level;
(4) Kuumbwa kwemakemikari uye michina yemagetsi;
(5) Chitupa chekubvumidzwa kubva kuboka revanhu uye siginecha yemuongorori.
2. Kuongorora kwenyama:
Pakuunza simbi yemugungwa, chinhu chinobatika chinofanirwa kunge chine chiratidzo chemugadziri, zvichingodaro.
(1) Mucherechedzo wekubvumidza nzanga;
(2) Shandisa pendi kugadzira kana kunamira mucherechedzo, kusanganisira tekinoroji paramita senge: cheto batch nhamba, yakatarwa giredhi giredhi, kureba uye hupamhi zviyero, nezvimwewo;
(3) Chitarisiko chakatsetseka uye chakatsetseka, chisina kukanganisa.
