| Abstract: | Shield tunneling has become a main construction method used for underground engineering, especially within weak soil and congested urban areas. With more and more built-up underground projects, it will be often faced with many engineering problems about crossing construction no matter what improvement is made in the tunnel shielding technology. The influence of tunnel shield crossing through an adjacent operating metro was paid much attention by lots of researchers at home and abroad now. A great deal of in-situ monitoring data observed from a case named Zhangyang to Pudian Tunnel No.2 of Shanghai was analyzed and studied. Its conclusion would be helpful for the future similar shield tunneling projects. |
