摘要
当同一市政道路下方同时规划有综合管廊及地铁隧道工程时,在论述两者协同施工可行性的基础上,结合地铁隧道施工过程、结构力学特性,统筹考虑施工的安全性、经济性与协调性,针对各种施工工法的特性提出地铁隧道与管廊协同建设施工方法。研究表明,当管廊工程与地铁盾构隧道建设时序同步时,应优先考虑两者共同设置于大直径盾构隧道内;当不满足共构条件,且地面具备临时占地、管线改移量小、交通可导改时,管廊可采用明挖法随地铁盾构隧道同步建设;当地面不具备明挖条件,仅具备设置盾构始发井及接收井的条件时,管廊可采用盾构法随地铁盾构隧道同步建设;当管廊与地铁盾构隧道不满足上述条件且受地层或者其他条件限制管廊无法采用盾构法施工时,管廊可采用暗挖法随地铁盾构隧道同步建设。该研究成果对类似工程设计和施工具有一定的借鉴意义。
When the same under the municipal road while planning a comprehensive utility tunnel engineering and the subway,on the basis of both collaborative construction feasibility,combining with the subway construction process structure and mechanical properties,economy and coordination as a whole the safety of the construction of the basic principle,according to the characteristics of various construction methods proposed subway interval with utility tunnel construction method research shows that when the utility tunnel engineering and construction of metro shield interval timing synchronization,priority should be given to both set in the large diameter shield tunnel When does not meet the constitutive conditions,and the ground with temporary covers an area of pipeline to move a little When the traffic can be changed,open cut method can be used for synchronous construction along the subway shield section.The local surface does not have the conditions for open cut,but only has the conditions for setting shield starting well and receiving well.Therefore,the pipe gallery can be built along the subway shield section by shield method.
