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 eliphansi ngokwedlulele ngu--35.8℃, izinga lokushisa elijwayelekile lenyanga ebanda kakhulu ngu-13.4℃, ubukhulu beqhwa obugqinsi bungu-21cm, kanti ukujula okuphezulu kweqhwa kungu-299cm. Indawo yomhubhe iyi-alpine ne-hypoxic, ingcindezi yomoya ingama-60% -70% kuphela womfutho womoya ojwayelekile, okuqukethwe komoyampilo emoyeni kuncishiswa cishe ngama-40%, nokusebenza kahle kwemishini nabasebenzi kuyancipha kakhulu. Umhubhe wakhiwe ngendlela yokubhoboza nokuqhunyiswa, futhi i-10 yokuthutha engenamkhondo i-shafts ethambekele isetshenziselwa ukusiza ukwakhiwa komhubhe omkhulu, okungukuthi, ama-shafts athambekele angu-3 asethwe emhubheni we-line I kanye ne-7 shafts ethambekele isethwe emhubheni womugqa we-II.
Ngokusho komklamo wenhlangano yokwakha, ukuhlelwa komsebenzi wokungena komhubhe nokuphuma kanye nendawo yokusebenza ye-shaft ethambekele kukhonjiswe kuThebula 1. Uma kucatshangelwa izinguquko kanye nokulungiswa ekwakhiweni kwangempela, indawo yokusebenza ye-shaft ethambekele ngayinye inezidingo zokwakhiwa ngesikhathi esisodwa kwe-inlet kanye nokuphuma komugqa I nomugqa we-II. Ubude bokungenisa komoya okuphezulu kwekhanda elilodwa kufanele kube ngu-5000m, futhi ukuphakama kwendawo yokusebenza kufanele kube ngu-3600m.
Izoqhubeka...
