摘　　要：以萧甬铁路绍兴东站及货场迁建工程,采用薄壁筒桩对铁路软土地基进行加固处理为例,介绍了筒桩的设计和施工工艺,并对已施工的薄壁筒桩路基进行沉降观测。结果表明,薄壁筒桩能有效地控制铁路软土路基的工后沉降。Taking the practical projects of Shaoxing East Station of Xiaoshan-Ningbo Railway and the freight yard relocation as the examples, thin-walled cylindrical pile was used as the reinforcement of the railway soft foundation. This paper introduced the design and construction technologies of cylindrical pile, and made observation on the settlement of the constructed thin-walled cylindrical pile foundation. The result shows that this kind of pile could control the post-construction settlement of railway soft foundation effectively.
