| Abstract: | In the paper,the three dimensional fast Lagrangain analysis method is developed based on the explicit finite difference method.The method can be used to analyze the elastic-plastic and large deformation problems;It can also be used to simulate the construction process.The excavation and reinforcement of a high slope of expressway in Jinan are simulated by three-dimensional fast Lagrangian method (FLAC-3D).The displacement field and the stress field are discussed in the process of excavation and reinforcement of the high slope,and the influence caused by the static hydraulic pressure is also analyzed.According to the monitor data of the scene,the simulation is credible.The results are useful and helpful for similar engineering. |
| Keywords: | Excavation of high slope Displacement of high slope Numerical simulation Slope monitoring |
