Prediction of Liquefaction and Countermeasure due to Groundwater Lowering Method in Osaka and Wakayama Plains
The influence of groundwater rising for the liquefaction potential in Osaka and Wakayama plains was examined using GIS in which a digital database of underground information provided by Kansai Geo-informatics Database was introduced. The detailed geotechnical properties were calculated and given to Holocene sandy and clayey deposits that are representative value in each digital mesh of 250m × 250m areas. Then, liquefaction safety assessments were carried out by estimating pumping possible quantity of Holocene sandy deposits and considering negative effect of them against consolidation settlement problem that will occur in Holocene clayey deposits underneath. The efficacy of groundwater lowering method against liquefaction of Holocene sandy deposits was verified.
