| 抄録（英）： |
In order to measure liquefaction-induced ground displacement easily, a precise photogrammetric system was applied to a large-scale liquefaction experiment in reclaimed land. Digital photographs were taken from radio-controlled helicopter flying over experimental site at a height of about 150m. Comparing the ground displacement measured by the precise photogrammetry with that obtained by optical surveying, it was found that displacement could be measured by the precise photogrammetry in sufficient precision. Comparing the precision in changes of evaluating information like control points and measured length, it was found that it is useful for evaluating the ground deformation due to liquefaction flow even in the case of hard condition.
