| Research Abstract |
We develop a new finite element method which can simulate the mechanical behavior of an undersea tunnel in order to evaluate the soundness of its lining concrete. Results of numerical analysis show that lining and ground can be detached by the increase of the water pressure. We also confirm that the decrease of the seepage water can lead the change of water pressure or expansion of plastic zone, but it has little bad influence on the soundness of lining concrete.
