Analysis of Comparing Static Load Experiment with Large Strain Test for Pile Foundation

Bearing capacity of pile foundation has a big influence on anti-earthquake capacity of pile foundation.Through a large number of studies on comparing the static load experiments with the large strain tests for the same pile, the accuracy and reliability for measuring ultimate bearing capacity of a pile with a large strain test are worked out and causes led to errors in large strain tests are analyzed . Also, some methods and proceedings for reducing errors in a large strain test are proposed.
