Abstract:By the construction for to prevent the lining concrete from corrosion/seepage in the two tunnel, it has been brought to light that there are the sulfate attack to the lining concrete in the souther part of the country. By the way of -much exploring hole with small-bore + few hole with big-bore', it's quite easy to look out for headwaters of seepage in the tunnel. By the simulated test for dry environment with high speed wind in tunnel, we have got the concrete materials with excellent stability in volume. The concrete materials display good property about resistance to corrosion/ seepage in the process of construction.
