APPLICATION OF PRE-STRESSED ANCHOR-ROD CROSS COUPLING IN SUPPORTING DEEP FOUNDATION PIT
-
Abstract
In this paper authors characterized stress and loading mechanism of pre-stressed anchor-rod cross coupling in supporting deep foundation pit.Finite element method is used to simulate stress distribution in foundation pit supported by such beam.The moment of flexure of the beam and displacement of surface layer are also calculated,which overcomes disadvantage of traditional methods.By comparing simulated results with traditional anchor-pile supporting method the authors concluded that it is an economic and reliable way to apply pre-stressed anchor-rod cross coupling when the end of slope-protection pile cant be driven into the foundation.
