1. ʻO Guanjiao Tunnel Project Overview

Aia ʻo Guanjiao Tunnel ma Tianjun County, Qinghai Province.He papahana hoʻomalu ia o ka xining -Golmudlaina hoʻonui o Qinghai-Tibet Railway.ʻO 32.6km ka lōʻihi o ka tunnel (ʻo 3380m ke kiʻekiʻe inlet, a ʻo 3324m ka kiʻekiʻe i waho), a he ʻelua mau ala pololei like me ka laina laina o 40m.ʻO ka awelika wela o ka makahiki ma ia wahi he -0.5 ℃, ʻo ka wela haʻahaʻa haʻahaʻa loa he -35.8 ℃, ʻo ka awelika wela o ka mahina anu loa he -13.4 ℃, ʻo ka mānoanoa hau kiʻekiʻe he 21cm, a ʻo ka hohonu o ka hau hau he 299cm.ʻO ka'āpana tunnel he alpine a me ka hypoxic,ʻo 60% -70% wale nō ke kaomi o ka lewa,ʻo ka oxygen o ka ea e ho'ēmiʻia ma kahi o 40%, a ua emi loa ka pono o nā mīkini a me nā limahana.Kūkulu ʻia ka tunnel ma ke ʻano o ka wili ʻana a me ka puhi ʻana, a ua hoʻohana ʻia nā 10 trackless transport inclined shafts e kōkua ai i ke kūkulu ʻana i ka tunnel nui, ʻo ia hoʻi, ua hoʻonohonoho ʻia nā 3 inclined shafts i ka tunnel o ka laina I a me 7 inclined shafts i hoʻonohonoho ʻia i ka tunnel. o ka laina II.

E like me ka hoʻolālā ʻana o ka hui kūkulu hale, ua hōʻike ʻia ka hoʻonohonoho hana o ke komo ʻana a me ka puka ʻana a me ka wahi hana inclined shaft ma ka Papa 1. E noʻonoʻo ana i nā hoʻololi a me nā hoʻololi ʻana i ka hana maoli, aia kēlā me kēia wahi hana inclined shaft i nā koi o ka hana like ʻana o ka inlet a puka o ka laina I a me ka laina II.ʻO ka lōʻihi o ka hoʻoheheʻe ʻana i ke poʻo hoʻokahi he 5000m, a ʻo ke kiʻekiʻe o ka wahi hana ma kahi o 3600m.

E hoʻomau ʻia…
