Abstract:
Due to of high-speed development of economy for the metropolis, the electric power system of predicament is overloaded. Because of the less restriction of the construction for early periods, the cut and cover construction of underground electric power system is adopted. In order to reduce the impact of traffic and environments for the metropolis, the shield tunnel method is used for the 345kV underground power cable duct construction to ensure the stability of power supply and the quality of electricity. By means of the case study, this article describes the how and the why of the lining resistance in a difficult situation of the high water, soil pressure and pernicious of SO4-2. The RC lining may be harmed by the rapid curve excavation. By careful strategy the durable of lining could be maintained. The case study is served as a reference for the similar construction in the future.
