Numerical Analysis of the Response of Buildings Close with Deep Foundation Pit as a Result of the Prestress Anchor

This article makes some numerical analysis of the digging of deep foundation pit by Ansys and some analysis of the response of buildings close with deep foundation pit as a result of the prestress anchors and stakes.By comparing the in- stances of anchors with stress and without it,the result shows that the anchor with stress is better for reducing the distortion of the groundsill.But we must pay attention to the angle and the position.Otherwise it will reduce the effect of the anchors and cause some cracks in the building when the angle is small and the position to fix is under the building.
