The relationship between the pile side friction resistance and pile tip resistance and the settlement is assumed to be ideal elastic-plastic,and the load transfer method is used to analyze the load-carrying characteristics of bored pile in practical projects,and the results are compared with the static load test results to prove the reliability of the analysis method and its parameters.Based on this,the bored pile is reinforced.The results show that the pile tip grouting mainly improves the pile tip resistance and has little effect on the pile side friction.The pile side grouting improves pile tip resistance and pile side friction more significantly.The ultimate load-carrying capacity of the pile is increased by 19%and 49%respectively after the use of pile tip grouting and pile side grouting.
