以北京地下直径线双线大直径（Ø11.6 m）盾构隧道的设计技术研究为背景，重点介绍了该盾构隧道的盾构选型、盾构管片结构计算、管片结构设计、管片防水设计等技术，并对该盾构隧道施工的设计要求做了简单叙述，对今后类似工程具有一定参考价值。

Based on the designing technology of double-line large diameter(Ø11.6 m) shield tunnel of Beijing underground diameter wire, this article emphased on the selection of shield tunnel machine, the structural calculation of the lining, the segment lining design and the water resistant technology, also demonstrated the designing requirements of the shield tunnel construction. These would be valuable reference for the future similar projects.
