Abstract

Abstract

Based on the deep foundation pit support project of a hospital in Beijing,this paper combined with measured data of prestressed bolt in pile-anchor support system,comprehensively analyzed the regular pattern with time by the different free segment of bolt.Under the same conditions,it is considered that the longer the free segment,the smaller the loss rate of the anchor prestress value.

- anchor,
- free segment
