Abstract: According to the condition of a bridge, a finite element was established to explore the potential failure mechanism of abutment sidewall cracking and sliping. Soil pressure was combined with live load and potential centrifugal force that might be generated due to small radius curve at the beg inning of the bridge, to simulate the most critical load condition. The results indicated ex cessive tension stress due to bending might had caused initial cracking and sliping in service.
