| Abstract: | During the high-strain in-place pile test,the accuracy of test results are influenced significantly by many detail steps including the treatment of pile head,the installation of sensors,the application of pile cushion,the appropriate lift of ball breaker and its beating.In this paper,the effect results of these factors are analyzed,and the corresponding treating measures are given.These measures can be used to improve the accuracy of in-site grouting piles test with high-strain method. |
