Evaluation of soil liquefaction risk on linearly structure considering the soil investigation locations

Abstract

An evaluation of soil liquefaction risk considering the soil investigation locations is applied to 12km long irrigation channel. The paper provides full procedures of geotechnical reliability analysis that include statistical analysis of site investigation data for site characterization, estimation of soil parameters from site investigation results. Liquefaction potential was modeled by the local estimation in addition to the general estimation that had been generally done. In addition, the liquefaction risk of an arbitrary point was evaluated by the reliability analysis on the liquefaction potential. It was shown that the reliability analysis by the local estimation was an effective method to the countermeasure plan to liquefaction on linearly structure.
