Abstract: To avoid making barriers for follow-up engineering and save from a trouble of law, the temporary anchor rods of foundation pit brace should be removed when them have no effects. After some analyses of load transfer behavior of anchor rod, and based on the results of field test, a type of technique of removable anchor for which the pull rod can be removed, is proposed. By setting separation layer between pull rod and slip casting body to remove pull rod, and by setting bearing body with pole to disperse load to slip casting body, this technique is realized. Actual engineering example shows that this technique is easy and feasible. Because of the stress in removable anchor rod is reasonable, its technical characteristics are higher than traditional anchor rod too.

Key words: foundation pit, anchor-pull brace, pull rod, removable anchor rod, noncohesive steel stranded wire
