Abstract During analysis of subsea tunnel stability, the influence of fluid should be considered to ensure veracity of simulation. But it is difficult and slow to couple fluid-mechanics. So effect of fluid is often omitted and only elasto-plastical analysis is done for tunnel, which causes some error. During the process of analyzing stability of Xiamen subsea tunnels, using FLAC-3D (Fast Lagrangian Analysis of Continua in 3 Dimensions), elasto-plastics analysis and fluid-structure coupling analysis are developed with fluid considering and non-considering. From the results of stress distribution, displacements and plastic zones of rock mass after excavation, differences are contrasted.
