摘　　要：随着我国城市道路的迅猛发展,软土地基处理中凸显出来的问题已越来越严重,在很大程度上影响着工程的整体质量、建设工期,以及工程造价。因此,加强对城市道路软土地基处理的技术研究显得尤为重要,有很强的现实意义。该文主要针对软土地基处理中的桩处理,分析了水泥搅拌桩、Y形沉管灌注桩、CFG桩(水泥粉煤灰碎石桩)三种不同桩型各自的特点和施工技术,可供相关人员参考。With the fast development of urban road in China, the problems in the soft soil foundation treatment have been more and more seriously, and have affected the overall quality, construction period and engineering construction cost of the projects to a large extent. Therefore, it is extremely important to strengthen the technical study of soft soil foundation treatment of urban road, and it has very strong realistic meaning. Mainly aiming at the pile treatment of soft soil foundation treatment, the article analyzes the different characteristics and construction technologies of three cement mixing pile, Y-shaped tube-sinking cast-in-situ pile and CFG(cement fly-ash gravel) pile, which can be referred for the similar projects.
