某公路隧道塌方原因分析及处治技术

摘要

以某高海拔、大型水电站库区复建公路隧道的一处典型隧道塌方体为研究对象,采用定性与定量相结合的研究方法,研究了隧道塌方原因,提出了合理的塌方处治措施,并成功地完成了隧道塌方处治.%Taking reconstruction of a typical collapse body of highway tunnel in a high-attitude & large-scale hydropower station reservoir area as the study object,the method combined qualitative and quantitative analysis was used to explore the causes of tunnel collapse herein,and then proper measures were put forward to treat the collapse successfully.
