Abstract:
In order to analyze the human comfort when vehicles passing through the transition section between bridge abutment and embankment, the vibration system of road-vehicle-human were put forward. On the basis of analyzing the present evaluation methods and criteria for human body vibration and comfort, the new evaluation method adopting piezoelectric acceleration sensor to measure the vertical acceleration of the human body was proposed according to the vibration characteristics. Take two existing expressways for example, this method was used to evaluate the human body comfort. The results show that the new method can objectively and accurately evaluate the human body comfort degree so as to provide a theoretical basis for the control of differential settlement of the transition section based on comfort properties. 5 tabs, 2 figs, 10 refs.
