贵阳轻轨2号线机小区间左线明挖隧道设计
摘要：本设计为贵阳轻轨2号线机小区间（机场站~小碧站）左线明挖段隧道结构设计。隧区处于贵阳市东侧，龙里县西侧。地处云贵高原，由中低山向丘陵过度地带，海拔高程多在1000～1500m之间，大部分地区相对高差在200m以内。机场站～YCK46+434段已由机场站先期施作完成，线路从YCK46+434处右偏下穿机场路匝道、贵新路及匝道填方路基围成的积水洼地、贵新路以及机场路旁加油站后沿着机场路敷设至小碧站。本册设计范围为YCK46+434～小碧站区间隧道，不车站，设计起讫里程为：左线ZCK46+434～+930。2（ZCK46+637。218=ZCK46+630。000 长链7。218m），全长513。418m，其中YCK46+434～+579段采用明挖法施工，YCK579～+930。2段采用暗挖法施工。左洞：纵剖面坡率依次为-8‰，-9。406‰，2‰，相应坡段长分别为48。4m，377。218m,10。27m。本次设计主要包括隧道结构主体设计与计算，内力计算并对衬砌结构进行配置钢筋，绘制相对应图纸。经详细检查验算，本设计方案合理可行，通过。81274

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。
