摘要：随着城市交通的发展，地铁已成为出行最为方便的交通工具。各个城市势必会进行大规模城市轨道交通建设。这一定会带来不同地铁线路间交叉和换乘问题，出现非常多的节点车站。受地下空间的限制以及人们换乘的需要,新建的地铁工程必须要近距离穿越既有地铁线路。其中下穿既有地铁线路工程利用非常广泛，特别是暗挖地铁车站下穿既有地铁隧道工程技术。虽然地铁研究已经十分先进，但对暗挖地铁车站下穿既有线地铁的隧道施工方面还缺乏研究。而隧道暗挖法在城市的地铁施工中得到了广泛运用。地铁车站是地铁中的交通枢纽，由于车站受地理位置的限制，不可能全都采用明挖施工，车站设计大多采用的是暗挖或明暗结合的方法，所以暗挖法建造地铁车站对于城市交通的发展具有很重要的意义。本设计通过对暗挖隧道的结构净空设计与主要尺寸拟定、结构内力计算、结构配筋设计与检算，使其验算和设计符合《地下铁道设计规范》，《混凝土结构设计规范》。本设计突出隧道暗挖的应用，体现了我国隧道的发展趋势。77548

The configuration design of Guiyang light railway line 2 Senlong interval’s left line bored tunnel

Abstract: With the development of urban transport, the subway has become the most convenient means of transport。 Each city is bound to carry out large-scale urban rail transit construction。 This will bring different subway lines between the cross and transfer problems, there are a lot of node stations。 By the constraints of underground space and the need for people to transfer, the new subway project must be close through the existing subway lines。 Which under the existing subway line project is very extensive use, especially the underground subway station under the subway tunnel construction technology。 Although the subway research has been very advanced, but the underground subway station under the existing subway tunnel construction is also a lack of research。 And tunnel excavation method in the city's subway construction has been widely used。 Subway station is the subway in the transport hub, due to the geographical location of the station restrictions, it is impossible to use all the excavation construction, station design is mostly used to conceal or dark and dark combination of the method, so the construction of subway station subway station for urban traffic Development is of great significance。 This design is based on the design of the hollow space and the design of the main dimensions, the calculation of the internal force of the structure, the design and calculation of the structural reinforcement, and the calculation and design of the tunnel are in accordance with the Code for Design of the Underground Railway and the Code for Design of Concrete Structures。 This design highlights the application of tunnel dug, reflecting the development trend of China's tunnels。
