| Research Abstract |
Slope failures sometimes occurred with windfall trees during typhoon. It is possible that the slope failures were due to ground softening around trees subjected to large wind load. This study clarified the mechanism of ground softening using model tests and in -situ tests. The experimental results showed that ground softening occurred in loose ground with fine contents around the tree root after cyclic loading.
