| 摘 要： | 本文基于空间非均匀地震动输入和拱坝三维动力有限元法，建立了拱坝在非平稳空间随机地震动场激励下的随机振动分析方法．以一实际拱坝为例，计算了非平稳随机地震动场作用下的拱坝随机地震反应，并与平稳随机地震动场的结果进行了比较．

| Abstract: | Based on the non homogeneous earthquake motion input and 3 D dynamic finite elemnt method,a random seismic response analysis method for arch dams excited by non stationary random earthquake motion field is proposed.An example is given for illustration.The calculated result of response is compared with that based on stationary field. |
