山岭隧道软弱围岩变形机理分析与处治对策

摘要

对国高网乐雅高速公路槽渔滩隧道左线软弱围岩地段产生大变形的机理进行了详细分析,以现场地质情况为依据,结合检测手段,发现产生变形既有地质情况的原因,也有施工质量缺陷的原因。根据变形机理,结合实际变形情况,针对性的提出合理、有效的处治方案,解决了工程实际问题。%The large deformation mechanism in the soft surrounding rock section of Caoyutan tunnel＇s left line is analyzed here in detail,which is in Leya Expressway from national expressway network.In the process of analysis,based on the geological conditions in sites and combined with detection measures,it is found out that the deformation is attributed to both geological conditions and construction quality defects.According to the deformation mechanism and combined with actual deformation conditions,the reasonable and effective solution is proposed to solve actual engineering problems.
