1. Guanjiao Tunnel Project Overview
Guanjiao Tunnel iri muTianjun County, Qinghai Province. Icho chirongwa chekutonga chexing -Golmudmutsara wekuwedzera weQinghai-Tibet Railway. Iyo mugero wakareba 32.6km (iyo inlet yakakwira 3380m, uye kureba kunze kwenyika i3324m), uye inzira mbiri dzakafanana dzakati chechetere ane mutsara wemutsara we40m. Paavhareji tembiricha mudunhu iri -0.5 ℃, yakanyanya kuderera tembiricha i -35.8 ℃, avhareji tembiricha yemwedzi unotonhora i -13.4 ℃, iyo yakanyanya kukora yechando i21cm, uye kudzika kwechando kwakanyanya 299cm. Nzvimbo yemugero ndeye alpine uye hypoxic, mhepo yemhepo inongova 60% -70% yehuwandu hwemhepo yemhepo, iyo okisijeni yemhepo inoderedzwa ne40%, uye kushanda kwemichina nevashandi kunoderera zvakanyanya. Iyo mugero inovakwa nekuchera uye nzira yekuputika, uye 10 trackless kutakura yakarerekera shafts inoshandiswa kubatsira kuvakwa kwemugero mukuru, ndiko kuti, 3 inclined shafts inoiswa mugero remutsara I uye 7 yakatemerwa shafts yakaiswa mumugero wemutsara II.
Maererano nekugadzirwa kwesangano rekuvaka, kurongeka kwebasa rekupinda uye kubuda uye kurerekera shaft nzvimbo yekushanda inoratidzwa muTebhu 1. Tichifunga nezvekuchinja uye kugadziriswa mukuvaka chaiko, nzvimbo imwe neimwe yakarerekera shaft yekushanda ine zvinodiwa zvekuvakwa panguva imwe chete yekupinza uye kubuda kwemutsara I uye mutsara wepiri. Iyo yakanyanya kureba yekufefetera musoro mumwe chete inofanira kunge iri 5000m, uye kukwirira kwenzvimbo yekushanda kunofanirwa kunge kuri 3600m.
