Pull-out Simulation of Post-Installed Anchors Embedded into Partially Grouted Enlarged Holes

摘要

The pull-out behavior of a post-installed anchor embeddedinto a partially grouted enlarged hole was sufficiently simulatedusing an FE model and the corresponding interface parameterswere obtained, then used to find out the effect of ①grout levelwithin such enlarged holes and ② depth of the hole enlargedpart on pull-out performance of such partially grouted anchors.
