【摘要】 海底隧道平面线位的选取是整个海底隧道工程规划和设计阶段的关键环节,为了综合考虑海底隧道平面线位对隧道建设经济、安全、技术适用性及环境的影响,从风险系数角度入手,找出各方面的致险因素,结合层次分析法,建立一套完整的海底隧道平面线位评估体系.将这套评估方法应用于厦门海底隧道,对拟取的4条平面线位进行综合评估,确定出最优线位,为海底隧道工程的规划选线提供一定的参考.更多还原

【Abstract】 The selection of planar line for subsea tunnel is a key part during the whole planning process in subsea tunnel construction.In order to consider the influence of safety,cost,technique application and environment on the planar line determination comprehensively,a variety of corresponding risk factors are found based on risk coefficient.A set of assessment system for subsea tunnel planar line is established with analytic hierarchy process(AHP) method.Finally,this system is successfully applied in Xiamen subsea tunnel,and four supposed planar lines are evaluated.Afterwards,the advantages and disadvantages of each planar line are given,which provides reference to other planned subsea tunnels.更多还原
