Program Type

Study for soil-structure interaction in liquefied soil with 3d effective stress analysis

液状化地盤における地盤と杭の相互作用について分析するために，三次元有効応力解析プログラムFLIP3Dを用いてE-Defenseによる振動台実験の再現解析を行い，液状化地盤における群杭の挙動について考察した．既往の実験で示されていた過剰間隙水圧の低下の度合いが群杭の外側の杭において大きい傾向を数値解析においても再現できていることを確認した．一方，全応力で比較すると杭に働く土圧は群杭における杭の場所によって大きな差が生じていないことも確認できた．
