Abstract
This study aims at discussing the S-wave velocity profile of the ground around Naha port. Both Ryukyu limestone layer and Shimajiri mudstone layer are deposited around the area. N-values obtained by the standard penetration test for Ryukyu limestone layer widely varies because of the variation of degree of consolidation of the layer. However, as the consolidation structures of the soil layer is destroyed in the process of the standard penetration test, it may not be adequate to evaluate the S-wave velocity profile of the ground from the N-values. We conducted microtremor array observation and obtained the S-wave velocity profiles by using the spatial autocorrelation method.
