Abstract
This study took Jiafengling tunnel as the typical study case. According to the geological exploration results, this paper chose the typical sections to layout the rational measuring holes for monitoring. The monitoring data were analyzed and put forward that the slope stability was affected with the tunnel excavation and the slope water state is the main factors of the slope stability. Numerical simulation for tunnel excavation was carried out by using MIDAS-GTS software, the tunnel excavation in displacement and strain change rules was analyzed, and the result shows that the excavation of the displacement and strain change is significantly more than that of not excavation, and tunnel portal section is the most important one of the area of collapse and crack failure, therefore, the tunnel portal stability is the critical problem in tunnel design and construction .关键词
