The purpose of this research is to investigate a relationship between ground displacement and seepage behavior on slopes. We have set up a filed monitoring system on the slope behind a structure, which is an important cultural asset in July 2004, and pore-water pressure, temperature and rainfall intensity are measured. Moreover, ground displacement is measured using optical fiber sensors. In this paper, monitoring results are explained. And, the influences of rainfall on ground displacement measurement are described.

Key Words: Ground displacement, Optical fiver sensor, rainfall, pore-water pressure
