Numerical simulation study on influence factors of the seepage volume of submarine tunnels

Bangshu Xu

Abstract

The influence factors of the seepage volume in submarine tunnels were studied by means of numerical simulation.A large number of models with different model scales and boundary conditions were built for the numerical simulation.The computed results showed that when the distance from the boundary to the tunnel profile was at least 7 times the tunnel diameter,an accurate seepage volume could obtained,and the fixed boundary makes the seepage volume be overestimated,while the free pore pressure boundary was underestimated.
