Abstract

In Washiodake landslide located in Nagasaki Prefecture, caisson piles are installed to prevent landslide movement.<br>The stress of reinforcing rod in the caisson piles have been monitored by a strainmeter attached to the rod for 15 years since they were first installed.<br>Recently, the strainmeter began submitting abnormal values due to the long-term usage.<br>Therefore, it is necessary to estimate the stress applied in caisson piles by methods other than reinforcing rod strainmeter.<br>First, precedent compression stress of a concrete core was evaluated using AE method (Kaiser effect). Meanwhile, current present stress state of a caisson pile was evaluated. According to the estimation, the values were within tolerance.
