概要:
金沢大学理工研究域環境デザイン学系<br />Horizontal ground displacements caused by liquefied ground flow were observed at reclaimed lands during the 1995 Hyogoken-Nambu earthquake. Many displacements were not due to the influence of the inclination of ground surface and movement of quay wall. The present paper aims to find the causes of the displacements mentioned above and to investigate how to estimate their directions and magnitudes. A method is proposed here to evaluate the spatial distribution of SPT N-value. Although this method is usually used to investigate a trend surface on altitude, it was applied to evaluation of the spatial hardness of soil layers. The gradient and azimuth of trend surface on SPT N-value were found using data of reclaimed lands in Kobe area. The boundary of geological stratum that was decided by the distribution of SPT N-value was easily estimated using the proposed method. Furthermore, it was clarified that the direction of horizontal displacement of ground surface was influenced by the inclination of boundary between soft and hard soil layers. It will be expected that this method is useful to estimate the liquefied ground at the level reclaimed land. 続きを見る
