Abstract

Abstract: This papre establishes the Finite Element model of soft rock channel by selecting proper creep model of soft rock.Taking a highway channel as an example ,influence of construction time of anchor rod and supproting structure on deformation and stress of channel structure is analyzed.The model of this paper can be used on other underground structures at soft rock region.

Key words: soft rock , channel , finite element method

摘要： 选用适当的软岩蠕变模型,建立了软岩围岩隧道的有限元计算模型,并以某修建在软岩地段的公路隧道为例,分析了隧道锚杆和支护施工的时间对其变形和内力的影响.另外,该模型也可应用于其它软土地下工程
