Numerical Investigation Of Liquefaction Mitigation In-Sandy Soils Under Earthquake Loading Using Vertical Gravel Drains., Marawan M. Shahien M. Shahein, Ahmed Nasr, Baher Mohamed Abd El Fattah

Journal of Engineering Research

Liquefaction is one of the most dramatic defects of granular soil. This phenomenon is mostly observed when loose sand is subjected to a dynamic load or earthquake. In this study, the liquefaction that affected the loose soil evaluated, and some recommendations are introduced. (2-D) Numerical analysis using Plaxis (8.2) was conducted to simulate the behavior of the loose soil under dynamic loads. The studied model was carried out on multi-layers soil supported by stone columns subjected to dynamic loads. It was found that stone columns enhanced the soil behavior and reduced the damage that occurred. Liquefaction of the loose soil …
