摘　　要：随着我国港口工程建设步伐向海外迈进,高震地区防波堤地震稳定性问题变得尤为突出,但国内分析防波堤地震响应的文献十分匮乏。基于FLAC-2D软件,探讨几何模型建立、边界条件设置及阻尼选取,对比对地基进行处理及未处理两种情况的地震响应结果,为其它工程提供相关参考。With the pace of domestic harbor construction to overseas, the seismic stability problem of breakwater has become particularly prominent in high intensity earthquake area. But domestic references about how to analyze the seismic response of breakwater are insufficient. Based on FLAC-2D , some remarkable problems about geometrical modeling, boundary condition and applying damping are discussed and results of seismic response analysis in the cases of foundation treated and untreated are compared, which can serve as reference for similar projects.
