| 概要 | ||||||
| 内容記述タイプ | Other | |||||
| 内容記述 | It is difficult that to set a clear standard concerning the design, because tunnels are excavated in various geotechnical conditions. Therefore, in general, the design is carried out still experientially, so it is required that analytical method that can appropriately reproduce the mechanics behavior on the natural ground. In this study, we tried excavation simulation analysis of shallow tunnel in multilayered ground using DEM, and the purpose of our research is established the analytical simulator in multilayered ground. Then, the focus of our research is actual collapse accident of tunnel, and we examined the presence of the collapse by setting conditions of underground water and the invert support, etc. We decided the analytical parameters by trying the simulation analysis of biaxial compression test using DEM, before we start the excavation simulation. As a result of the simulation, an analysis model has collapsed when underground water exists and non-closing invert as the actual phenomenon. | |||||
