| Abstract: | Taking the engineering of Erqi Yangtze River of Wuhan as an example,we carried out the self-balanced loading test for pile bearing measuring,according to the results of which,we studied the bearing behavior of the pile and characters of its loading transfer.We also describe the whole process of confirmation of the shaft force and the skin friction of pile by the method.The experiment result proves that this method has a good application prospect in the static load test of the super-long drilled pile. |
| Keywords: | super-long drilled pile self-balanced loading test skin friction of pile pile tip resistance |
