摘　　要：近年来预应力钢筒混凝土管(PCCP)在国内长距离输水工程中应运越来越广泛。随着国内广泛的应用,加之各地区地质条件的不同,PCCP管道安装遇到了不同地质条件下施工工艺多样化的安装方法。文中介绍了在复杂地质条件下采用龙门吊施工工艺,具有适用于野外施工作业、施工成本费用较低的特点,在保证施工进度、施工质量、节约施工成本方面取得不错的经济和社会效益。In recent years the PCCP have been adopted more and more extensively in long distance water diversion projects in our country. In pace with the extensive use of this pipe, and under various geological conditions in different regions, the assorted construction technique methods to install PCCP are applied. The article introduces the construction technique to install PCCP by the gantry crane under complex geological conditions. This method possesses the feature of having the low construction cost, is suited under field construction operation and obtains good economic and societal benefit to ensure construction schedule and construction quality, and to save the construction cost.
