• LIQUEFACTION POTENTIAL EVALUATION FOR CEMENT-TREATED SANDY GROUND CONSIDERING THE SPATIAL VARIABILITY OF MATERIAL PARAMETER

抄録

This paper presents a probabilistic method for assessing the liquefaction potential of cement-treated sandy ground, which is an anti-liquefaction ground improved by cement-mixing. The proposed probabilistic method considers the inherent spatial variability of unconfined compressive strength in the cement-treated ground, the random testing error of unconfined compression tests, and uncertainties in the regression analysis to estimate the liquefaction resistance in cement-treated sandy ground. The percentage of liquefaction zone in the ground and the liquefaction potential index are calculated to evaluate the potential of liquefaction in cement-treated sandy ground. Finally, the effectiveness of cement-mixing for sandy ground to prevent liquefaction is discussed based on the result of the application to three construction sites of cement-treated sandy grounds.
