摘　　要：混凝土中的水分和空气中水分的相互作用,当风干的程度(速度)小于混凝土内部浸入表层水分时,砼表面会呈现"泛潮"。泛潮是隧道防水的难点,它直接影响到隧道的渗漏和衬砌砼表面的外观质量。The water in the concrete and the water in the air interacts with each other. When the wind-drying speed is slower than the permeating speed of water in the concrete, the surface of the concrete will appear ＂wet＂. To prevent this is the hard point of concrete lining works, which directly influences the water permeation of the tunnel and the outer quality of the concrete.
