The invention relates to the field of an oil-gas pipeline system, discloses a method for processing frozen soil in pipeline repairing operation pit, and aims to solve the technical problem that the heat utilization rate of a frozen soil burning and melting method in the prior art is low. The method comprises the steps of locating the position of a defect point welding seam of a pipeline; determining the center line of the pipeline, making a first mark on an intersection point of the center line and the defect point welding seam, and making second marks on the center line by taking the intersection point as the center at preset intervals; placing stoves at positions, which are spaced from the center line by a first preset distance, of two sides of the pipeline according to the first mark and the second marks; erecting a frozen soil burning and melting tent at the peripheries of the pipeline and the stoves; controlling the stoves to be in a working state so as to burn and melt the frozen soil. According to the method disclosed by the invention, the technical effect of increasing the heat utilization rate during frozen soil burning and melting is achieved.
