Popis: The energy method was used to analysis the deformation of acrylic waterproof membrane under the uniform load and to calculate the maximum central deflection according to the clamped circular plate. Because the shape of the deformation of waterproof membrane bulge was similar to semi-ellipsoid, the curve length corresponding to the maximum central deflection was calculated by elliptic equation. According to the curve length, the deformation could be calculated under the different water pressure and membrane thickness. Comparing the deformation with the maximum elongation ratio, the water pressure and the thickness of waterproof membrane which ensure the safety could be calculated in theory. If the water pressure was known, the thickness of spray-membrane could be determined in the tunnel engineering.
