Abstract
This paper reports on design method of bridge foundation against ground flow caused by liquefaction. This method allows us to estimate the displacement due to ground flow by FEM analysis and to design bridge foundation. We verified the design method using the past case histories of damage caused by earthquakes, including Hyogo-ken Nambu Earthquake, and we also examined the applicability of the design method to the ground in Tokyo area. Moreover, this design method can be applied to design countermeasures against ground flow for existing bridge foundations.
