The invention relates to a structure for preventing an automobile ramp from excessively settling in a soft soil foundation, the automobile ramp is arranged at the position 300mm below the elevation of a base, a fir pile is arranged on a retaining wall on each side of the automobile ramp, the tip diameter of each fir pile is larger than 120mm, the distance between every two fir piles is 1m, and the fir piles are arranged in a plum blossom shape. A sandstone mattress layer is arranged at the top of the cunninghamia lanceolata piles. The excavator is used for pressing the cunninghamia lanceolata piles at the bottom of the automobile ramp to treat the soft soil foundation, so that serious engineering quality problems of cracks, water seepage and the like caused by excessive settlement of the automobile ramp are solved, the problem of asynchronous settlement of the automobile ramp and a basement is effectively solved, and the method is simple, practical, economical and feasible and has a great popularization prosp
