广州地铁六号线3标段盾构管片设计关键技术

On the key technology of the segment design in the shield machine of 3 bid-section along the No.6 Guangzhou subway

通过对广州地铁六号线盾构3标段管片设计、选型及施工的研究,论述了在盾构隧道曲线段的通用环管片和左右转管片的楔形量、转弯能力计算方法和设计技术,该文提供的设计计算方法对类似工程的管片设计具有参考价值。

According to research on the segment design, the selection of models and the construction of 3 bid-section along the No. 6 Guangzhou subway, the paper illustrates the taperness of the general ring＇s segment and the right and left twirling＇ s segment, the calculation method of the cornering ability, as well as the design technique. And the paper provides reference the design calculation method for the segment design of similar construction.
