Abstract

The left tube and the right tube of the shield tunnel on Guangzhou Metro Line 6(Datansha Station-Ruyifang Station) crosses Pearl River once respectively.During the construction,such measures as the application of earth pressure balance mode,boring parameters optimization,controlling of muck quantity,grouting quantity,position of shield machine and boring speed and muck improvement are adopted to ensure that the shield machine successfully crosses over the Pear River.
