摘要
本文首次将空间随机地震动场输入用于拱坝随机振动分析之中,与拱坝三维动力有限元法结合,完成了三维拱坝在空间随机地震动场作用下的随机振动分析方法及算法的研究;另外考虑动力和静力的叠加,提出了三维空间随机地震动场的拱坝抗震可靠度分析方法,最后编制了相应的程序,对小湾拱坝进行了抗震可靠度分析,并与随机变量的结果进行了比较。
The method of seismic response of a 3-D arch dams to a spatially correlated seismic excitations is developed in the paper. In addition, the analysis method of seismic reliability of a 3-D arch dams to spatially correlated seismic is put forword with consideration of the combination of both dynamic and static actions. The calculated results for Xiao Wan Arch Dam by using this method are compared with that of the traditional method with random variable.
