Abstract

Canals are important as lifeline facilities that supply water to urban areas. However, the countermeasure in popular use, such as improvement of entire liquefiable ground of the canal by chemical feeding, is hugely expensive. Against this background, the authors investigated a reasonable liquefaction countermeasure for an existing flume canal using sheet-pile with drain. In this study, several shaking table tests in the 1 g gravitational fields were conducted, and the experimental reproducibility of the analysis was checked to confirm the effectiveness of the proposed countermeasure. The results indicated that the proposed method was effective in reducing the deformation (i.e., uplift/sinking displacement and inclination) of the canal, and good reproducibility for dynamic effective stress FEM analysis using LIQCA code with respect to the results of the experiment was confirmed.
