摘　　要：结合广州市某大型供水管线工程,介绍了软基强化技术措施以及大口径球型承插式钢管的施工方法,该种新型接口钢管采用承插安装、内外两道焊缝连接的方式,具有操作方便、接口强度高等优点,值得推广应用。By taking a large-scale water supply pipeline in Guangzhou for example, the consolidation technology for soft soil foundation and the construction of ball-type spigot and socket pipe with large caliber were introduced. This new type steel pipe adopted the spigot and socket joint, with connection of both inner and outer weld seam, which had the advantages of convenience for operation and high strength of joint, and was worth popularizing.
