| Abstract: |
The objective of this paper is to study the dynamic impacts of moving light-rail trains on viaduct bridges and the vibrations induced on the surrounding ground. The study is based on theoretical analysis and field experiment. The theoretical study is performed in two stages using a 2D interaction model of "train-bridge" system for obtaining the dynamic loads of moving trains on the bridge piers, and a 2D dynamic model of "pier-foundation-ground" system for analyzing the vibration responses of the surrounding ground. In the field experiment, the dynamic responses of bridge piers and the ground accelerations are measured at different distances under different train speeds. |
