Discussion on Treatment Method of Special Stratum Roadbed in Lanzhou Region

近年随着兰州市市政道路建设步伐不断加快,针对兰州地区分布的大厚度高湿陷黄土层、黄河两岸河低阶地上的软土层以及不同范围分布的大厚度垃圾土等特殊性地层,在路基处理方面仍存在很多问题。结合工程实践,对特殊性地层的路基处理方法进行探讨,有关经验可供相关专业人员参考。

With continuously speeding up the construction step of the municipal roads in Lanzhou City in recent years,there are still many problems in the roadbed treatment of the great-thickness high-collapsible loess layer distributed in Lanzhou Region,the soft soil layer on the low terraces at both banks of Yellow River and the special stratum with the great-thickness rubbish soil distributed in the different ranges.The article discusses the roadbed treatment method of the special stratum according to the engineering practice.The relative experience can be referred for the relevant professional members.
