挤扩支盘桩在建筑、工业厂房等工程中得到了较快的发展和应用，但在送电线路工程方面，国内还没有见到应用的实例。介绍在某500 kV双回路送电工程上，首次使用挤扩支盘桩基础的情况，将其单桩下压、抗拔极限承载力与同桩径、桩长的钻孔灌注桩进行比较，并进行了技术经济性分析，得到挤扩支盘桩受力特性非常符合送电线路铁塔基础的受力特性、有较好的推广应用价值的结论。
擠擴支盤樁在建築、工業廠房等工程中得到瞭較快的髮展和應用，但在送電線路工程方麵，國內還沒有見到應用的實例。介紹在某500 kV雙迴路送電工程上，首次使用擠擴支盤樁基礎的情況，將其單樁下壓、抗拔極限承載力與同樁徑、樁長的鑽孔灌註樁進行比較，併進行瞭技術經濟性分析，得到擠擴支盤樁受力特性非常符閤送電線路鐵塔基礎的受力特性、有較好的推廣應用價值的結論。

Squeezed branch and plate pile have never been used in transmission line projects in China,though it gained quickly development and application in architecture and industry workshop projects.Squeezed branch and plate pile’s first application in transmission lines is introduced in this paper. The characteristic values of vertical ultimate bearing capacity of the single pile are computed and compared with the values of column bored pile,and the technical and economic analysis is made between column bored pile and squeezed branch and plate pile. Finally,the conclusion of squeezed branch and plate pile deserved to be popularized.
