STUDY ON PRECISION OF THE ESTIMATED AVERAGE SHEAR-WAVE VELOCITY BASED ON PS LOGGING DATA IN NAGOYA CITY AREA

Abstract

In this paper, precision of the estimated average shear-wave velocity by geomorphologic classification and by boring data is shown based on PS logging data in Nagoya Area. It is shown that estimated precision of average shear-wave velocity based on the geomorphologic classification become at the same level than that of average shear-wave velocity based on boring data, by performing a regression analysis using data in limited area. For estimation of the average shear-wave velocity distribution that integrated geomorphologic classification with boring data, the author propose a method to use estimated precision of average shear-wave velocity for a weighting factor.
