For improving the behavior of the conventional micropile, a new-concept waveform micropile was suggested. The waveform micropile has a modified construction process, and the waveform shape on the pile shaft is formed through jet grouting. The waveform micropile provides additional shaft resistance due to the shape of the waveform grout body, which was confirmed through a series of experiments and numerical analysis. In this study, 96 waveform micropiles were applied to a bridge abutment construction site, and their field applicability was evaluated based on the construction process and loading test. The paper discusses the details of the design and installation of the waveform micropile, including the loading test results.
