System and method for reinforcing loose soil slope embankment in highland strong earthquake region

The invention relates to the technical field of roadbeds, in particular to a reinforcing system and method for a loose soil slope embankment in a highland strong earthquake area. Wherein the upper part of the slope embankment is provided with a first plastic area, the lower slope toe of the slope embankment is provided with a second plastic area towards a natural slope at a lower elevation, a bidirectional geogrid is horizontally arranged in the slope embankment, a single-row drilling pile is arranged between the first plastic area and the second plastic area, the upper part of the single-row drilling pile is positioned in the slope embankment, and the lower part of the single-row drilling pile is positioned in loose soil; a side slope reinforcing and protecting device is arranged on an embankment side slope of the slope embankment. According to the reinforcing system for the loose soil slope embankment in the plateau strong earthquake area, the slope embankment is comprehensively reinforced through the drill
