| Abstract: | Through the case histories by using high-strain insepection for the drilled piles with end grouting,the principle of high-strain inspection and the testing method are briefly introduced.According to the inspection data and the testing results the effect of the end grouting is analyzed,and the relationship between pile-side resistance and pile-end resistance for the limit bearing capacity of pile are discussed.The concept of optimal pile-end resistance is put forward. |
