摘要
在陡倾岩层中存在的主要工程问题为陡倾地质构造带来的围岩大变形,其对地下工程设计和施工带来了巨大不便。基于重庆某高速公路隧道工程,主要对陡倾岩层中隧道变形影响进行研究,详细分析了地层倾角、岩层厚度、岩性和界面参数等因素对隧道变形的影响,并得出了相关结论。
The main engineering problem in steep dip strata is the large deformation of surrounding rock caused by steep dip geological structure,which brings great inconvenience to underground engineering design and construction.Based on a highway tunnel project in Chongqing,this paper mainly studies the influence of tunnel deformation in steep dip strata,analyzes the influence of factors such as dip angle,rock thickness,lithology and interface parameters on tunnel deformation in detail,and draws relevant conclusions.It has important reference significance to the displacement and deformation research of similar engineering.
