摘要
郑州至西安铁路客运专线是我国也是世界上首次在黄土地区修建的第一条时速350km的无砟轨道客运专线。黄土湿陷性是该线遇到的主要特殊工程地质问题。如何做好基底的处理工作关系到整个工程的施工质量。基于此,该文主要结合实例对湿陷性黄土地区路基地基中的灰土挤密桩的应用进行了探讨。
The passenger railway line from Zhengzhou to Xian is the first ballastless track passenger railway line with 350 km time per hour built in the collapsible loess region in China and also in the world.The collapsible loss is the main and special engineering geological problem met in this line.How to treat the foundation base well is related to the construction quality of the whole project.Based on this,the article mainly discusses the application of the lime-soil compaction pile in the roadbed foundation of collapsible loess region by the practical cases.
