| 摘 要： | 采用动力离散元法对一个实际工程的支座承载能力进行了分析，并分别考虑了静力和地震两种情况。结果表明，地震对桥墩的极限承载能力有直接的影响。在地震区进行桥墩设计时，必须评价桥墩在地震作用下的动力稳定性。

| Abstract: | The stability of a bridge depends on the bearing capacity of footing abutment formed by back filled rocks. It is, thus, necessary to determine the bearing capacity of footing abutment . Dynamic distinct element method is adopted to estimate the bearing capacity of a practical footing abutment, considering static and seismic cases. The results indicate that seismic acceleration has a great influence on bearing capacity of footing abutment. It is suggested that dynamic stability of bridge footing be assessed when the bridge is built in seismic region. |
