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.
