Structural Design of Right Tunnel Underground Tunnel in Guiyang Light Rail Line

Abstract  Guiyang City Rail Transit Line 2 Phase II Airport Station ~ Xiaobi Station is located in Guiyang City Nanming District. Among them, the airport station ~ YCK46 +434 section has been completed by the airport station ahead of the line from the YCK46 +434 right side down through the airport road ramp, your new road and ramp fill roadbed surrounded by water, (YCK46 + 434 ~ +930.2), the line spacing of 10 ~ 13.90m, the depth of the rails 0 ~ 16.1m, YCK46, the length of the tunnel between the road and the subway station, + 434 ~ +579 section using the open digging method construction, YCK46 +579 ~ +930.2 paragraph using dug construction. In this graduation design, the design of the tunnel clearance was designed. According to the engineering analogy, the structural dimensions were worked out. The internal force and deformation analysis were carried out. The reinforcement and calculation of the tunnel lining structure were carried out. The reinforcement scheme was drawn. The construction plan was written and the construction flow chart.
