摘　　要：上海市石洞口第二电厂高240m钢筋混凝土外筒、双钢内筒烟囱采用自爬式液压顶升倒装施工工艺,取得了58d完成1号钢内筒顶升工作的高速度和钢内筒中心偏差+3.47m、相对倾斜偏差1/6900的高质量,施工技术达到国际先进水平。A 240m chimney with exterior R. C. shaft and interior doublesteel shaft has been well con- structed by the bydraulic self-climbing and reversible lifting method. The whole construction work has been finished completely within 58 days. And its No. 1 interior steel shaft's lifting work has been done with high speed efficiency. Besides, it is to be noted that the shaft's central deviation is merely +3. 47ram, while its relative slant deviation is only 1/6900. Therefore, it is generallyrecognized as a high quality job and up to the standard of international level.
