摘要： 以青岛胶州湾第二海底隧道黄岛端斜井为研究对象，在总结长大隧道斜井纵断面和横断面设计要点的基础上，综合考虑该斜井辅助施工、防灾救援、运营服务的需要，提出满足要求的斜井纵断面和横断面设计方案。斜井纵坡选用200 m长10%+60 m长3%组合坡度，施工期间限速5 km·h-1，运营期限速20 km·h-1;斜井横断面的设计需要同时满足施工期、应急救援、运营服务不同功能建筑限界的需求；斜井建成后作为服务和应急救援隧道保留，将极大提高突发情况发生时的应急救援能力，也为隧道后期运营养护提供便利。

Abstract: This paper presents a case history an inclined shaft at Huangdao end of Qingdao Jiaozhou Bay Second Subsea Tunnel. The design aspects of the longitudinal profile and the cross section of the inclined shaft for the long tunnel are introduced. Considering the needs of the auxiliary construction, hazard prevention and rescue and operation services of the inclined shaft, the design procedure of the longitudinal profile and cross section of the inclined shaft meeting the requirements is proposed. The longitudinal slope of the inclined shaft is a combined slope of 10% (200 m) + 3% (60 m). The speed limit during construction is 5 km per hour and 20 km per hour during operation. The design of inclined shaft cross section needs to meet the needs of building clearance with different functions during the construction, emergency rescue and operation services. After the completion, it will be retained as a service and emergency rescue tunnel, which will greatly improve the emergency rescue capacity in case of emergencies and provide convenience for the later operation and the maintenance of the tunnel.


Key words: jiaozhou bay second subsea tunnel, inclined shaft, cross section, profile, construction clearance, comprehensive benefit
