| Abstract: | This article introduces the shield launching option on a small-radius curve on Beijing subway Line 10 between Guomao Station and Shuangjing Station to bypass a guard stake.In the construction,the launching angle of the shield was modified to achieve a minimum radius of 250 m for shield turning,and a series of measures inside and outside the tunnel was adopted.Through careful construction and careful organization,shield launching on a small radius curve succeeded. |
