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 kukwirira 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 gumi isina trackless yekufambisa shafts yakatemerwa inoshandiswa kubatsira kuvakwa kwemugero mukuru, kureva, 3 yakatemerwa shafts yakaiswa mugero remutsara I uye 7 yakatemerwa shaft yakaiswa mugero. yemutsara II.
Maererano nekugadzirwa kwesangano rekuvaka, kurongeka kwebasa rekupinda uye kubuda uye kurerekera shaft nzvimbo yekushanda inoratidzwa muTebhu 1. Tichifunga nezvekuchinja uye kugadziriswa mukuvaka chaiko, imwe neimwe yakarerekera shaft nzvimbo yekushanda ine zvinodiwa zvekuvakwa panguva imwe chete yekupinda uye. kubuda kwemutsara I uye mutsetse II.Iyo yakanyanya kureba imwe-yemusoro yekufemesa kunofanirwa kuve 5000m, uye kukwirira kwenzvimbo yekushanda kunofanirwa kunge kuri 3600m.
