| Abstract: | By the GeoFBA-2D and elast-plasticity theory,linking to practice of Hanjialing large span road tunnel of the Shenyang-Dalan motorway,a FEM simulation was conducted and its stability was analyzed.By these analysis,safety during the time of the tunnel operating will be ensured.At the same time,the calculation results and relevant conclusion can make up blankness of analysis on large span tunnel,and offer the important reference basis for design and construction of tunnel. |
