The structural design of left line open trench tunnel in the line 2 of Guiyang light rail
Abstract:The design for the Guiyang light rail line 2 between the small area (Airport Station ~ small blue station) Zuo Xianming Dig tunnel structure design。 The tunnel area in Guiyang City, East, on the west side of the county。 Located in the Yunnan Guizhou Plateau, from the Low Mountain hilly transition zone, elevation in 1000 ~ 1500m, the relative elevation in most areas within 200m。 The airport station to YCK46+434 from airport station in advance the completion, the lines from the YCK46+434 right down through the airport road ramp, your new road and ramp embankment surrounded by water depressions, your new road and Airport Road gas station along the road to the airport after the laying of Xiaobi station。The book design range is YCK46+434 ~ Xiaobi station tunnel, no station, destination: Design mileage left line ZCK46+434 ~ +930。2 (ZCK46+637。218=ZCK46+630。000 long chain 7。218m), full-length 513。418m, YCK46+434 ~ +579 section of the open excavation method construction of YCK579 ~ +930。2 by tunnelingmethod。 Left hole: longitudinal section slope rate of -8 thousand, -9。406 m, 2 m, the corresponding slope length of 48。4m, 377。218m, 10。27m。 This design mainly includes the design and calculation of the main structure of the tunnel, the internal force calculation and the configuration of the lining structure reinforcement, draw the corresponding
drawings。 After detailed examination and checking, the design scheme is reasonable and feasible。
