摘要建立了基于ABAQUS软件的海水-土-隧道结构体系有限元模型,采用Airy微小振幅波动理论,对静、动水压条件下不同埋深海底隧道地震反应特性进行了比较。结果表明：动水压力作用下隧道结构的水平向加速度及相对水平位移分别比静水压力作用下的相应值大1.1～1.4倍和1.8～2.3倍；随着隧道埋深增加,隧道结构的应力、水平位移逐渐减小,动水压力影响系数K_D有减小的趋势,也即达到一定埋深时,动水压力对隧道结构的地震反应没有影响；隧道拱肩和拱腰处的应力反应明显大于其他部位,拱肩和拱腰处为隧道结构的最危险部位。

Abstract：Based on the theory of Airy minute amplitude of vibration, A finite element model for sea-soil-tunnel system is established on the basis of the software of ABAQUS. The seismic responses of under sea tunnels to of effects analysis hydrodynamic and hydrostatic pressures under different buried depths are compared. The results show that, the horizontal acceleration and relative horizontal displacement is 1.1~1.4 and 1.8~2.3 times respectively under hydrodynamic pressure than hydrostatic pressure. With the increasing buried depth, the stress and displacement as well as the corresponding impact factor of hydrodynamic pressure K_D decrease, that is, the hydrodynamic pressure has no effect on seismic response when it reaches certain depths.The stress in spandrel and haunch is significantly larger than that in the other parts so that the spandrel and haunch are the most dangerous parts of the tunnel.

Key words： undersea tunnel seismic response hydrostatic pressure hydrodynamic pressure buried depth
