STUDY ON EVALUATION METHOD OF MONETARY LOSS DUE TO LIQUEFACTION DAMAGE

The newly developed method was proposed for the evaluation of monetary loss and repair cost induced by liquefaction in damaged public facilities at Urayasu, Chiba, after The 2011 off the Pacific coast of Tohoku Earthquake. This study explores the relationships between the degree of liquefaction (D sub(cy)) and extent of the exterior damage. The facilities were categorized by several parameters such as the measured settlement, D sub(cy), and liquefaction index (P sub(L)), and the probability density function was introduced to represent the general relationship between the repair cost of the exterior damage states and the parameters defined for each category. The evaluation method and estimated repair cost were verified by the numerical comparison of the current liquefaction method with introduced probability density function through the scenario earthquakes.
