A combustor liner structure of a gas turbine engine equipped with fins comprises an injecting plate(4), an effusion plate(2) and a fin(10). The injecting plate is installed at an outer side of the combustor liner and includes at least two injecting holes(8). The effusion plate is installed at an inner side of the combustor liner in parallel to the injecting plate such that the effusion plate is in contact with combustion gas and allows jetted cooling fluid to be effused through at least two effusion holes(6). The fin is disposed between two of the injecting holes. The fin has a first side connected to the injecting plate and a second side connected to the effusion plate. The fin has an oval cross section, and a major axis of the fin is larger than a diameter of the injecting hole and smaller than a distance between the injecting holes.
