Visualization of liquefaction phenomenon by coupled CAE analysis of MPS and DEM

The mechanism of liquefaction and the factors that cause liquefaction have already been examined and evaluated both analytically and experimentally, and liquefaction countermeasure construction is being implemented based on these findings. However, there are no cases in which the mechanism of liquefaction generation in the original ground and the effects of liquefaction countermeasures were visually examined and evaluated.
This study theoretically visualizes the mechanism of liquefaction generation and evaluate the behavior of particles in the ground. 
Specifically, MPS-DEM coupled CAE analysis is used to visualize the inside of the ground when an external force acceleration is applied, simulating seismic waves, and reveal the behavior inside the ground. The MPS-DEM coupled CAE analysis succeeded in visualizing the liquefaction phenomenon by applying an external force acceleration that simulates a seismic wave to the ground modeled three-dimensionally.
This study is expected to clearly show the mechanism of liquefaction generation, and to contribute to the design and accountability of 欧洲杯足彩app下载_欧洲杯下注平台-【直播*网站】 efficient and economical liquefaction countermeasures, regardless of the field of specialization.
