Analysis on Application of Miniature Pile Pre-Stressed Anchor Cable in Designing Deepen the Deep Foundation Pit

Abstract:

Based on the practical deep foundation pit example in Zhengzhou, with the increasing foundation design burying depth, the foundation pit’s is designed to be deepened before foundation ditch support being finished. Comparing the technical risks and controlling the monitoring process, an analytical method which takes the upper supporting structure as gravity retaining wall was proposed. For digging the side slope, we use Miniature pile pre-stressed anchor cable to enhance the lower part of the slope soil, which is a successful completion of the deepen design and construction of the foundation pit. It brings significant economic benefits, and also provides much reference value to the deepen design of the similar foundation pit.
