Abstract

The pulse discharge anchor is a method to increase the capacity of anchors using electric discharge geotechnical technologies, which is also known as pulse discharge and electric-spark technologies. The pulse discharge anchor has bulbed bond length that is expanded by high voltage electrokinetic pulse energy. 24 anchors were installed in the weathered soil and sandy clay at the Geotechnical Experimentation Site at Sungkyunkwan University in Suwon, Korea and attached strain gauge at 10 anchors. The numerical predictions by Beam-Column analysis were compared with observed measurements in a field load test.
