MECHANICAL ERROR ANALYSIS OF PILE BEARING CAPACITY OBTAINED FROM HIGH-STRAIN DYNAMIC TESTING

In this paper,many factors to determine load capacity of piles by high-strain method for pile test are analyzed.And the relations between dynamic wall friction or toe resistance and actual load capacity of pile inmathematical model are also studied.The error sources of high-strain method in the processing to determine load capacity are pointed out herein.This study has a certain significance in the popularizing high-strain method to determine load capacity of pile.
