Summary:The invention discloses a forced ramming construction method, and in particular relates to a forced ramming construction method for filling foundation soil with Xigeda soil in a high slope area. In the method, the Xigeda soil is backfilled to a high slope zone of which the gradient is no less than 1:1.75, and then construction processes of main ramming, repeated ramming and full ramming are adopted; before the main ramming is performed, main ramming points are arranged in an area where the Xigeda soil are backfilled, the main ramming points are arranged in a shape of quincunx in the backfilling area, and the space between adjacent main ramming points is between 4 and 6 meters; the energy level of the main ramming is 6,000Kn.m, the ramming times of each point is between 10 and 14 times, and the average subsidence amount of the last three strikes is less than or equal to 8 centimeters. Through the process, the height of the gradient can reach over 8 meters, the internal friction angle of the high slope is no le
