谈高铁隧道穿越严重湿陷性黄土地层地基处理

Exploration on the treatment of the high-speed railway tunnel through serious collapsible loess soil base

从湿陷性黄土的定义入手,结合工程实例,并根据其地质条件和施工环境提出了相应的处理方案和检测办法,通过试验验证得出处理方案可行且能满足基底要求和隧道暗挖区的施作要求。

From the definition of the collapsible loess soil, combining with engineering practice, and according to its geological conditions and construction environment, it puts forward the corresponding processing program and testing methods. The experimental results obtain that treatment is not only feasible but also can meet the tunnel base requirements and construction requirement of undermining tunnel district.
