摘　　要：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 need of urban development and the lack of land, the requirement for power cable tunnel construction technology is more and more high. Combining with the cable tunnel engineering practice, the risk of earth pressure balance shield in the long distance and deep overburden is analyzed and corresponding control measurements is put forward in the paper. The technical feature of different stage of short distance accross the operating tunnel is also researched. Through the application in the shanghai Expo power cable tunnel project, a set of risk control technology is accumulated, which can be referenced by similar project.
