摘　　要：昆明某钢筋混凝土现浇筒体烟囱高120 m,建于1958年。经对烟囱的地基基础、筒壁倾斜、筒壁混凝土强度、钢筋混凝土保护层厚度、钢筋锈蚀情况、隔热层及内衬等进行检测,计算筒身承载力并比较地震频率,对烟囱的可靠性做出评级,提出了加固措施和维护建议。The 120 m high cast-in-place reinforced concrete chimney in Kunming city was built in 1958. Foundation, wall inclination, wall concrete strength, thickness of the reinforcing steel protection layer, corrosion of reinforcing steel, heat-insulation layer and inner lining were detected, bearing capacity of chimney body was calculated and earthquake frequency was analyzed, to assess stability of the chimney. Relevant strengthening measures and maintenance method were proposed.
