摘要
青岛海底隧道团岛二路匝道与左线隧道交叉口段为变截面特大断面,隧道埋深8～21 m,隧址处工程地质复杂,地表建筑物密集,确保建筑物和施工安全至关重要。对该段隧道开挖方案的选择和采取的技术措施进行介绍。
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.
