Abstract
Grouting effect is directly related to the construction safety of a submarine tunnel. This paper, by using numerical simulation method, focusing on the submarine tunnel with constant water head under the conditions of different grouting circle thicknesses, different grouting circle seepage coefficients and different water drainage modes, calculated and analyzed the tunnel's water inflow and the lining's external water pressure. And then the result obtained from numerical simulation was compared with that obtained from axisymmetric analytical solution. The analysis and comparison results show that: ( a ) different tunnel waterproof and drainage modes have significant influences on the lining's external water pressure;( b) the radial scope of grouting circle has a certain influence on tunnel's water inflow and lining's external water pressure, but not obvious; ( c) the permeability coefficient of grouting circle has greater influence on tunnel's water inflow and lining's external water pressure.关键词
