Abstract:

Article Preview

By use of the microseismic monitoring system, the dynamic response of punched pile construction of bridge pile foundation is studied and discussed for the first time. Wave data of loads acting on the construction is group-collected by means of the microseismic experiment on site. Then the waveform, vibration frequency and energy of testing data are analyzed. On the basis of the results, the weaken rules of vibration acceleration and energy are studied, and the effect of impact energy on the vibration velocity is analyzed. It shows that impact energy attenuates exponentially with the distance from the epicentre. The conclusion establishes the theoretical basis for studying the vibrant characteristic of punched pile construction, and provides valuable reference for engineering practice to take effective measures to reduce construction vibration.
