    • Abstract
  • Based on the testing results from single-pile vertical compression static load experiment on three borehole injection piles for a bridge of highway at Anqing city of Anhui Province, the paper analyses the pile's axial force transmission and side resistance properties, as well as analysis Q-s curve of the static load experiment, and relevant mechanism, the paper also discuses the borehole formation method, and the effect of mud circulation, etc. on engineering properties of the injection pile.The result indicates the characteristics of bearing capacity of bridge borehole injection pile in mudstone foundation and the failure mechanism.
