摘要
青藏铁路察尔汗盐湖路基下和路基边的盐溶洞,给铁路安全运行造成了极大的威胁。文中介绍了铁路通过的察尔汗盐湖区的地质环境条件和盐湖路基面临的主要环境工程地质问题,阐述了盐溶溶洞形成的机理和危害特点,采用注浆法治理病害收到了很好效果。
The karst caverns below and on the side of the subgrade of Qarhan Salt Lake along Qinghai-Xizang Railway exert great threats to railway safety operation. This paper introduces geological environmental condition of Qarhan Salt Lake and the main environmental engineering geological problems of the subgrade. It narrates the forming mechanism of salt-dissolved karst cavern and its harmful characteristics and gets the conclusion that grouting receives good effect for treatment of disease.
