地铁与综合管廊统筹设计

Integrated Design of Subway and Utility Tunnel

地铁与综合管廊作为城市中网络化建设的重大市政工程,所处地下空间具有高度的相似性和重合性,因此,统筹规划设计有利于地下空间的利用和工程投资的节约。然而,早期的地铁工程没有为综合管廊预留建设条件,造成交叉段管廊功能削弱等一系列问题。基于目前南京市轨道交通线网和地下综合管廊规划,全面梳理了两者的建设时序和空间关系,研究了各种情况下地铁与综合管廊协调建设的关键技术对策,供类似工程参考。

Subway and utility tunnel are the major municipal engineering projects in the urban network construction.The underground space occupied is highly similar and coincident.A coordination planning and design can effectively utilize underground space and save engineering investment.The early subway project did not reserve conditions for the construction of utility tunnel,resulting in a series of problems such as weakening the function of utility tunnel.Based on present Nanjing rail transit network and Nanjing underground utility tunnel planning,comprehensively sorts out the construction temporal and spatial relation between the two,studies the key technical solutions for the coordinated construction,provides a reference to related projects.
