摘要
成武高速公路张坪隧道软弱碳质板岩段初期支护变形、失稳,对失稳原因进行现场勘察、分析,提出了相应的处理措施,同时对处理效果进行评价,以此为类似工程提供参考和借鉴。
In this paper in view of the Zhangping Tunnel on Chengdu-Wuxian Expressway, the site surveys are conducted at its soft carbonaceous slate sections for deformation to initial support and its instability, reasons and proposed countermeasures to be taken are analyzed, meanwhile, the treatment effect is evaluated, which could provide some reference and good lessons for the similar projects.
