摘要
Anchor pull-out tests were performed on seven instrumented full-scale low-pressure grouted anchors installed in weathered soil at the Geotechnical Experimentation Site at Sungkyunkwan University. Anchors were 165 mm in diameter and embedded 9 to 12 m in weathered soil. Four were compression type and three were tension anchors. Performance tests, creep tests, and long term relaxation tests were performed and the results are presented. The characteristics of grout-soil and grout-strand interface were investigated and presented. From the measurements, a load transfer mechanism for tension and compression ground anchors was investigated and evaluated by a simple beam-spring numerical model.
