A STUDY ON COUNTERMEASURES AGAINST LIQUEFACTION-INDUCED GROUND FLOW BEHIND SEAWALLS
The purpose of the present study is to develop effective and economical measures for the reinforcement of existing seawalls and for the improvement of the ground behind the seawalls to prevent the occurrence of large ground displacement due to the flow of liquefied soil. The author proposed countermeasures, where steel sheet piles were driven behind the existing seawalls to prevent and to reduce the liquefaction-induced ground displacement. The effectiveness of the developed countermeasures was examined by model experiments under a centrifuge condition of 50g. Based on the experimental studies, the author proposed a method to estimate the external forces on countermeasure walls from the liquefied soil for the earthquake resistant design of the walls.
