| Abstract: | FEM calculation results and the time series of in-situ measures for the entrance of Longjin tunnel on the Chong-Zun expressway are presented. A FEM model is established to simulate the deformation behaviors of the tunnel. The anchors are simulated with the anchorage elements,while the cement lining and the steel-arc shelf are simulated with the straight beam elements. The results show that the deformation behavior of the surrounding rock mass is controlled by unsymmetrical loadings during the process of construction. It is proposed that not only the in-situ dynamic measurements but also the analysis of FEM be important for successful construction of the tunnel. |
| Keywords: | tunnel engineering unsymmetrical loading tunnel dynamic monitoring FEM simulation information-oriented construction |
