浅谈连拱隧道复杂地质情况下浅埋偏压段施工

Simple discussion on shallow burying bias section construction under complex geologic situation

湖南常吉高速公路殿会坪隧道出口地质情况复杂,偏压严重,半明半暗及半隧半路段施工过程中出现坡面溜坍、山体持续位移等险情,文章通过介绍其处理和施工过程,就复杂地质条件下双连拱隧道半明半暗、半隧半路段的施工顺序、工艺及方法、特殊情况的处理等作了较为详尽的说明,并提出了相关看法和建议。

Because of complex geologic situation and serious bias of Dianhuiping tunnel exit ,it appears dangerous situation such as hillside landslide, hillbody continual displacement in the course of construction of half bright and half dark, half tunnel and half road construction. Through introducing the process of disposal and construction, the author gave a exhaustive explain, and brought forward correlative opinion about the construction order, technique, method, disposal to especial situation of half bright and half dark, half tunnel and half road section of double connective arch tunnel under complex geologic situation.
