Research Abstract

In this study, a horizontal static loading test is carried out to understand the resistance characteristic of an abutment. From the test results, it is understood that the maximum strength becomes larger in the case of the specimen with the backfill soil. However, the weakest part of the abutment is the basement of the vertical wall regardless of the backfill soil. Furthermore, as the results of the numerical simulation, we can estimate the load-displacement relation curve until the steel main bars in the vertical wall yielded.
