摘要
对南京纬三路过江隧道主要地质问题进行分析与风险评估,重点对复合地层的适应性、盾构机换刀的可行性以及盾尾密封的可靠性等方面提出施工对策,为工程的前期筹划方案制定及盾构机选型提供技术依据,也为工程实施过程中规避地质重大风险提供指导。
The main geological conditions of Weisanlu river-crossing shield-bored tunnel in Nanjing are analyzed and assessed.Countermeasures are proposed in terms of how to cope with the complex geology,how to replace the cutting tools and how to ensure the tail skin sealing.The paper can provide reference for the execution of the project.
