摘要
文章根据隧道塌方的特点,对广西境内某二级公路隧道塌方区提出两种处治方案并进行数值分析,得到了不同施工阶段下隧道各个部位的位移变化规律及围岩塑性区变化特点,同时对两种方案的处治效果作出了评价。
According to the characteristics of tunnel collapse,this article proposed two treatment programs and conducted the numerical analysis for the tunnel collapse area of a secondary highway in Guangxi,obtained the displacement variation rules of different tunnel parts under different construction stages as well as the variation features of surrounding rock plastic zones,at the same time it evaluated the treatment effects of these two programs.
