Development of Removable-Strand Compression Anchor
초록
For temporary excavation support in private land area, the strand of ground anchor should be removed In order to get permission to install anchors. The extractable or removable-strand compression anchor system was developed and evaluated by a series of pull-out load tests. 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, Four anchors are the compression type anchors and three are the tension anchors. Performance test, creep test, and long term relaxation test were performed and presented. Load distributor was developed in order to distribute large compressive stresses in grout.
