Abstract

Abstract

Based on the deep foundation pit support project in Beijing,combined with measured data of prestressed bolt in pile-anchor support system,this paper comprehensively analyzed the regular pattern with time by the different tensioning sequence of bolt.Under the same conditions,it is considered that the prestress loss rate of the anchor is the smallest in the adjacent tensioning sequence
- prestress loss,
- anchor,
- tensioning sequence
