In Japan, studies on liquefaction-induced flow started just after the 1983 Nihonkai-chubu earthquake and were accelerated after the 1995 Hyogoken-nambu earthquake. Several prediction and countermeasure methods have been proposed. At Metropolitan Expressway, detailed study was conducted to evaluate the safety against the flow. Then, four sites were selected to reduce the effect of the flow by applying a countermeasure. The applied method was to install steel pipes between bridge foundations and sea walls.
