摘要: 布袋注浆桩是一项新的软土地基加固技术，应用于深厚层和夹硬层的软土加固，具有明显的优势。结合甬台温铁路深厚层软土地基加固，介绍了布袋注浆桩的加固机理、设计、施工、质量检测方法和标准等。检测结果表明，布袋注浆桩成桩质量良好，加固后，地基沉降得到有效控制，满足设计要求。Abstract: Bag-grouting-pile is a new technique to improve softsoil,it has obvious advantage to improve the deep thick or forcedly interlayer softsoil. Based on the case of the softsoil improving in Yong-Tai-Wen railway engineering project, the mechanism, design and construction of this new technology are introduced.
