Abstract:
The inner diameter of shield tunnel segment has a significant effect on integral performance of tunnel structure. In this paper, the stateoftheart of the selection of inner diameter of shield tunnel segment in China and abroad is studied in terms of tunnel service life, tunnel construction clearance, track laying and technoeconomic benefit. The study results show that: 1) The tunnel construction clearance should be 5 300 mm so as to guarantee vibration reducing effect of track bed in special section. 2) The inner diameter of shield tunnel segment should be enlarged to more than 5 800 mm so as to guarantee the tunnel service life, provide space for secondary lining of tunnel and reduce maintaining cost obviously.
Key words: urban rail transit, shield tunnel, segment inner diameter, tunnel service life, tunnel construction clearance, technoeconomic benefit
