1. Incamake yumushinga wa Guanjiao

Umuyoboro wa Guanjiao uherereye mu Ntara ya Tianjun, Intara ya Qinghai. Numushinga wo kugenzura xining -Golmudkwagura umurongo wa gari ya moshi ya Qinghai-Tibet. Umuyoboro ufite uburebure bwa 32,6km (ubutumburuke bwinjira ni 3380m, naho ibyoherezwa mu mahanga ni 3324m), kandi ni imirongo ibiri ibangikanye igororotse ifite umurongo wa 40m. Ubushyuhe buri mwaka mu karere ni -0.5 ℃, ubushyuhe bukabije ni -35.8 ℃, impuzandengo y’ukwezi gukonje cyane ni -13.4 ℃, uburebure bwa shelegi ntarengwa ni 21cm, naho ubujyakuzimu bukabije ni 299cm. Agace ka tunnel ni alpine na hypoxic, umuvuduko wikirere ni 60% -70% byumuvuduko usanzwe wikirere, umwuka wa ogisijeni wikirere wagabanutseho 40%, kandi imikorere yimashini nabakozi iragabanuka cyane. Umuyoboro wubatswe nuburyo bwo gucukura no guturika, naho imiyoboro 10 itwara inzira itagira inzira ikoreshwa mu gufasha kubaka umuyoboro munini, ni ukuvuga ko ibiti 3 byegeranye bishyirwa mu murongo w’umurongo wa I naho ibice 7 byegeranye bishyirwa mu murongo wa II.

Ukurikije igishushanyo mbonera cy’ubwubatsi, gahunda yimirimo yo kwinjira no gusohoka no gusohokera hamwe n’ahantu hakorerwa imirimo ya shaft irerekanwa mu mbonerahamwe ya 1. Urebye impinduka n’ibihinduka mu iyubakwa nyirizina, buri gace gakorerwamo shaft gafite ibyangombwa byo kubaka icyarimwe icyinjira n’isohoka ry’umurongo wa I n'umurongo wa II. Uburebure ntarengwa bwo guhumeka umutwe bugomba kuba 5000m, naho ubutumburuke bwakarere bugomba kuba bugera kuri 3600m.
