| Abstract: | The intersection of Qingdao Seabed Tunnel Tuandao Erlu Ramp and the left tunnel is a super large section tun- nel with buried depth of 8 - 21m, where complex geological condition is made worse by the concentrated surface building, therefore, it is of great necessity to ensure the safety of the building and construction. The paper gives an introduction of the selection of the excavation scheme and technical measures. |
