According to the present invention, the shape of a passage in an intake-air duct communicated with the suction side of the intake-air filter is regulated so that snow is heaped up in the intake-air duct, and accordingly, the volume of snow reaching the intake-air filter is reduce in order to prevent the intake-air filter from clogging, and to prevent the flow rate of intake-air into a gas turbine from being lowered. In order to attain the above-mentioned purpose, there is provided, according to the present invention, an air-intake method for a gas turbine, in which intake-air,taken from a fresh air intake port is fed downward through a second intake-air duct in a substantially vertical direction, and then is fed in a substantially horizontal direction. Thereafter, dust is removed from the intake-air within an intake-air filter chamber, and then, is led into the gas turbine.
