1. Uhlolojikelele Lwephrojekthi Yomhubhe waseGuanjiao
Guanjiao Tunnel itholakala Tianjun County, Qinghai Province.Kuyiphrojekthi yokulawula ye-xining -I-GolmudUmzila wokunweba we-Qinghai-Tibet Railway.Umhubhe ungu-32.6km ubude (ukuphakama kwe-inlet kungu-3380m, futhi ukuphakama kokuthunyelwa kwamanye amazwe kungu-3324m), futhi kuyimigudu emibili eqondile ehambisanayo enezikhala zemigqa engu-40m.Izinga lokushisa elijwayelekile lonyaka esifundeni ngu--0.5 ℃, izinga lokushisa elincane ngokwedlulele ngu--35.8 ℃, izinga lokushisa elijwayelekile lenyanga ebanda kakhulu lingu-13.4℃, ubukhulu beqhwa obugqinsi bungu-21cm, kanti ukujula okuphezulu kweqhwa kungu-299cm.Indawo yomhubhe iyi-alpine ne-hypoxic, ingcindezi yomkhathi ingama-60% -70% kuphela womfutho womoya ojwayelekile, okuqukethwe komoya-mpilo emoyeni kuncishiswa cishe ngama-40%, nokusebenza kahle kwemishini nabasebenzi kuyancipha kakhulu.Umhubhe wakhiwa ngendlela yokubhoboza nokuqhunyiswa, futhi i-10 yokuthutha engenathrekhi isetshenziselwa ukusiza ukwakhiwa komhubhe omkhulu, okungukuthi, ama-shaft athambekele ama-3 asethwe emhubheni we-line I kanye nama-shaft athambekele angu-7 asethwe emhubheni. womugqa II.
Ngokusho komklamo wenhlangano yokwakha, ukuhlelwa komsebenzi wokungena komhubhe nokuphuma kanye nendawo yokusebenza ye-shaft ethambekele kukhonjisiwe kuThebula 1. Uma kucatshangelwa izinguquko kanye nokulungiswa ekwakhiweni kwangempela, indawo ngayinye yokusebenza ye-shaft ethambekele inezidingo zokwakhiwa kanyekanye kwe-inlet kanye ukuphuma komugqa I nomugqa II.Ubude bokungenisa komoya okuphezulu kwekhanda elilodwa kufanele kube ngu-5000m, futhi ukuphakama kwendawo yokusebenza kufanele kube ngu-3600m.
