摘要/Abstract

摘要： 胶州湾第二海底隧道具有超长、超大、超深、地质复杂、通风排烟困难、疏散救援难度大、两岸接线复杂、建设条件限制多等诸多特点。为了科学、安全、经济地建设胶州湾第二海底隧道，结合项目特点，对超长海底隧道的选址、工法、埋深、断面布置、通风排烟、疏散救援等关键问题进行研究，得出以下主要结论： 1）超长海底隧道总体设计应突出地质选线理念，这是降低建设与运营风险、控制投资和保障工期的关键； 2）结合具体地质和建设环境条件进行多工法比选、分段选择适宜的施工方法并确定合理埋深，是超长海底隧道总体设计的重要内容； 3）胶州湾第二海底隧道海域段采用2条主线隧道+中间服务隧道的布置方式，在海域段主线隧道顶部设置风道，并创新提出2.5段通风方案，利用服务隧道兼作新风通道，解决了超长海底隧道的通风难题； 4）隧道两端洞口设置管理中心，在服务隧道洞口设置应急管理站，并利用服务隧道、人行及车行横通道、盾构段疏散楼梯和下层纵向疏散通道组成完善的疏散救援系统，可保障超长海底隧道运营安全。

Abstract: The Second Jiaozhou Bay subsea tunnel is featured by super length, super size, super depth, complicated geological conditions, difficult ventilation and smoke extraction conditions, difficult evacuation and rescue conditions, complicated connection to the road network on both coasts, and restrictions on construction conditions. In this study, the authors study on 〖HJ5mm〗key issues of the superlong subsea tunnel, including the location, construction method, overburden, arrangement in tunnel, ventilation and smoke extraction, evacuation and rescue, in order to construct the Second Jiaozhou Bay subsea tunnel in a scientific, safe and economic way. The following main findings are concluded: (1) The concept of selecting the tunnel alignment based on the geological conditions shall be emphasized in the general design of the superlong subsea tunnel, which is key to reducing the construction and operation risks, controlling the investment and guaranteeing the construction period. (2) In the general design of the superlong subsea tunnel, it is important to compare different construction methods, select appropriate construction methods for different sections of the subseal tunnel and determine the reasonable overburden according to the specific geological and construction environment conditions. (3) The subsea section of the Second Jiaozhou Bay subsea tunnel consists of twin main tunnel tubes and one service tunnel tube. The air passage is set at the top area of the subsea section of the main tunnel tubes, the innovative 2.5section ventilation plan is put forward, and the service tunnel is also used as the fresh air channel, which solves the ventilation problem of the super-long subsea tunnel. (4) A management center is set up at each portal of the tunnel, an emergency management station is set up at the portal of the service tunnel. Moreover, a complete evacuation and rescue system, which consists of the service tunnel, the pedestrian/vehicle cross passages, and the evacuation stairs and the longitudinal evacuation channel in the lower part of the shieldbored section, is arranged. In this way, the operation safety of the superlong subsea tunnel is guaranteed.

Key words: subsea tunnel, general design, selecting tunnel alignment according to geological conditions, service tunnel, construction method selection, ventilation and disaster prevention
