Large diameter bridge pile construction by vibration hammer——A new technique for large diameter bridge pile construction;

In order to offer theoretical support for the research on amplitude modulation mechanism of vibration exciter,the paper tries to find out,based on the study of dynamics performance of vibration hammer,the regular pattern affecting piling efficiency as a result of amplitude of vibration exciter.

Automatic vibration hammer is designed according to resonance theory.

This paper presents the selection of vibratory hammer types for construction of the pile foundations of Dashengguan Changjiang River Bridge in Nanjing and the problems and solutions to the problems encountered in application of Model APE400B tandem vibratory hammers to the construction of the Bridge.

For this purpose,large vibratory hammers with an excitation force of more than 2 300 kN had to be used to complete the installation of the piles.

The problems existing in the operation of the vibrating strike hammers of electrical precipitator in Huaneng Beijing Thermal Power Plant and the possible reasons are analyzed.

Analyze the influence of acceleration of EP and the distribution of acceleration,generating by common vibrating strike hammer\'s types,qualities and material\'s elastic modulus,by using the FEM.
