| 摘 要： | 京石客运专线设计时速350km/h,路基工后沉降控制要求严。为满足线路安全承载和正常运营的要求,采用CFG桩复合地基作为该项目主要的地基加固处理措施,以提高地基的承载力和稳定性,减少地基变形。该文结合京石项目,主要介绍了复合地基的施工技术及桩基检测,为同类工程提供借鉴。

| Abstract: | Beijing-Shijiazhuang PDL is designed at speed 350km /h. The settlement control of subgrade after construction is required strictly. CFG pile composite foundation is the major foundation reinforcement measures in the project to improve the foundation carrying capacity and stability,reduce foundation deformation. Combined with the Beijing-Shijiazhuang Project,the article mainly describes the construction technology of composite foundation and the inspection and testing technology of the pile foundation to provide a reference for similar projects. |
