Abstract:Research purposes: This paper introduces the alignment and the general upgrading of Guizhou—Guangxi Railway(Guiyang—Liuzhou),including the upgrading measures,research on main technical standards,the comparison and selection of upgrading schemes,ruling gradient,speed target value and number of main track,as well as upgrading effect,for the purpose of providing the reference to the upgrading of electrified railway.
Research conclusions: The Guizhou—Guangxi Railway is upgraded as Grade I electrified railway with singkle track, reversing condition for double tracks.The additional second track from Liuzhou to Luoman will be built.The ruling gradient is 6‰ and the ruling gradient is 1 3‰ in the section with double locomotive traction.The driving load is 3 800 t.The 160 km/h speed target value is desined for the Liuzhou—Jinchengjiang section and 140 km/h speed target value is designed for the Jinehengjiang—Longli section with some design margin.
