The invention discloses a reinforcing method and structure of a bottoming steel-reinforced concrete column, and the reinforcing method comprises the following steps: when the bottoming steel-reinforced concrete column is poured, firstly, filling a gap between a structural scabbling surface and a steel rib with a micro-expansion high-strength grouting material; initial setting of the micro-expansion high-strength grouting material; and concrete is poured on the initially-set micro-expansion high-strength grouting material. According to the construction technology of the bottom steel reinforced concrete column, the bottom gap is filled with the micro-expansion high-strength grouting material, and concrete is normally poured after the grouting material is initially set, so that the purpose of improving the forming quality of the bottom steel reinforced concrete column joint is achieved. 本发明公开一种起底钢骨混凝土柱的加固方法及结构，该加固方法方法包括：起底钢骨混凝土柱浇筑时，先用微膨胀高强度灌浆料将结构凿毛面与钢骨之间的缝隙灌满；微膨胀高强度灌浆料初凝；在初凝的微膨胀高强度灌浆料上浇筑混凝土。本发明提出的底钢骨混凝土柱施工工艺，先用微
