摘　　要：新建连盐铁路地处沿海地区淤泥质土层,地基处理困难。主要通过现场试验,确定沿海地区淤泥质土层水泥搅拌钉形桩的施工参数;通过沉降观测和成桩检测,确定了钉形桩处理淤泥质土层软基的效果和施工参数。这可为类似工程提供借鉴。The newly-built Lianyungang-Yancheng Railway is located in the muddy soil layer of the coastal area,and the foundation treatment is difficult. In this paper,the construction parameters of cement mixing nail pile in muddy soil layer of the coastal area are determined by field test. Through settlement observation and pile-forming test,the treating effects of nail pile on muddy soft soil foundation and the construction parameters are determined. It could be served as a reference for similar projects.
