摘　　要：厦门海底隧道是我国目前修建的最长的海底隧道,隧道及两岸接线工程位于福建省厦门地区。该地区潮汐现象多样,水文条件复杂,历年最大潮差达6.92m,多年平均潮差4.01m,在计算过程中应该考虑潮汐的影响。利用厦门海洋工程勘测中心的海流监测数据,考虑潮汐荷载循环变化过程中衬砌的疲劳损伤过程,用有限元方法模拟分析应力渗流耦合作用下隧道潮汐荷载对隧道衬砌和围岩稳定性的影响,研究成果对海峡海底隧道修建工程有所借鉴。Xiamen subsea tunnel is the longest one which is under construction in China at present. The tunnel and its connection projects are located in Xiamen, Fujian Province. Tidal phenomenon is multiple in this region, and the hydrological condition is complex. The maximum tidal range is 6.92 m in the past years, and the annual average tidal range is 4.01 m. The effects of the tide should be considered when numerical simulations are conducted. Using the monitoring data from the Research Centre of Ocean Engineering, considering the fatigue damage process of lining during tide changes, the influence of tidal load on the stabilities of lining and surrounding rock under hydro-mechanical coupling are analyzed by finite element method. The conclusion will benefit for future subsea tunnel design and practice.
