随着城市发展的需要及土地的缺乏,对电力电缆隧道施工技术提出越来越高的要求。结合电力电缆隧道工程的实践,本文分析了土压平衡盾构在长距离深覆土推进时存在的风险,并提出了相应的控制措施,研究了近距离穿越已运营隧道的各个阶段的技术特点。通过在上海世博电缆隧道工程的应用,积累了一些风险控制技术,可供类似工程参考。 With the needs of urban development and the lack of land, higher and higher requirements are placed on the construction technology of power cable tunnels. Combined with the practice of power cable tunneling project, this paper analyzes the risk of EPB shield in advancing long distance deep overburden, and puts forward corresponding control measures, and studies the technical characteristics of all stages of traversing the operating tunnel. Through the application of the cable tunnel project in Shanghai World Expo, a number of risk control technologies have been accumulated for reference of similar projects.
