Abstract: Low strain reflected wave method is a kind of common and important method in bridge pile test.Due to the theoretical defects and different geological conditions and other factors,test results may be not absolutely reasonable by low strain reflected wave method sometimes,and it often rely on the experience of testing personnel at this time.In addition,individual differences of pile physical parameters can also cause deviation of test result.This paper used the finite element numerical simulation method, analyzed the influence that the four physical parameters(pile length,diameter,elastic modulus and densi-ty)on pile reflection time of low strain reflected wave testing and got the concrete influence rule.The re-sults provide theoretical support and reference for pile testing.
