Description

Many shaking table tests were carried out to investigate seismic performance of retaining walls, but there are few examples of shaking table tests focusing on resilience performance of the retaining walls. In this study, a long-term shaking table test of unreinforced and reinforced soil retaining walls was conducted to compare the resilience performance. From the test results, it can be confirmed that the unreinforced retaining wall collapsed with a relatively small excitation energy due to the ground yielding, but the reinforced soil retaining wall did not collapse even when a relatively large excitation energy was applied, and showed high resilience performance.
