Abstract

The objective of this study is to estimate the motion amplification of bank of irrigation ponds by surface wave exploration and microtremor measurement. In this study, four types of the irrigation ponds were classified.<BR>S-wave velocity of bank is small in the ponds situated in plain and large in the ponds situated in the foot of the mountain or mountain. However, with regard to S-wave velocity of alluvium, the difference in types of the ponds is small.<BR>The relation between S-wave velocity of bank and height of bank has positive correlation. Similarly, the relation between predominant period and height of bank has positive correlation. But, the relation between amplification and predominant period of bank has negative correlation.<BR>Motion amplification of bank is strongly affected by the vibration characteristics of the foundation and the bank.
