Summary:The invention provides a roadbed step excavation method, and relates to the technical field of roadbed excavation. The roadbed step excavation method comprises the following steps: step 1, preparation work: carrying out construction lofting near a construction roadbed, and installing temporary protection walls on two sides of a roadbed road; 2, roadside cleaning is conducted, specifically, a constructor is matched with a construction machine to conduct bottom cleaning, paving, leveling and slope finishing, and a structure affecting step excavation construction is dismantled; thirdly, the slope surface is compacted; step 4, excavating layer by layer; the water content and the compaction degree of padding at the bottom of the step of the old roadbed need to be detected in time after the step is excavated, and if the water content of the padding is too large or the compaction degree is obviously insufficient, the padding is replaced. According to the roadbed excavation method, the roadbed slope surface is compac
