【Abstract】 The waterproof mechanism and current development situation are discribed on the flexible waterproof material, such as polymer modified asphalt waterproof materials, polymer waterproof materials, polyurethane waterproof coating etc, and the cement-based capillary crystalline rigid waterproof materials. The development situation of waterproof work in railway tunnels is analyzed. The waterproof layer construction process of fexible waterproof material and rigid waterproof materials are compared. The application of cement-based capillary crystalline waterproof materials in railway tunnel waterproof engineering is explored in this paper.更多还原
