[CS2-30] 地震発生に伴う軟弱地盤上盛土内部の動的挙動解明を目的とした実験的研究
キーワード:液状化、アーチ効果、軟弱地盤、盛土、動的挙動
The Tohoku earthquake occurred on 11th March 2011 led to catastrophic devastations including liquefactions underneath embankments which was located on the impermeable ground. Many researches focused on the liquefaction occured at ground have been conducted before 2011. However, this huge earthquake led to the liquefaction inside embankment, therefore the research focusing on the liquefaction inside embankment would be important for preparedness of the coming huge earthquakes but such few researches have been done at this moment. This research focuses on the initial stress distribution and aim to research the relationship between liquefaction occurrence and initial stress condition.
