中文摘要：
阐述近期大连理工大学抗震研究所在大坝抗震分析方面所取得的研究成果,为了提高大坝结构静动力分析的计算精度与效率,提出多边形单元的计算技术与奇异应力场计算方法,该方法使应力计算成果较有限元法有很大的改进,且计算工作量比较节省。
英文摘要：
The recent progress of the research which is conducted by the Faculty of Infrastructure Engineering,Dalian University of Technology is briefly introduced.To enhance the accuracy and efficiency of the static and dynamic stress analysis for dam structures,the calculation technique for exploiting salient functions of polygon elements and the method for evaluating singular stress field has been developed.Compared with the finite element analysis,these achievements results of stress analysis have been greatly improved.Meanwhile,the computational effort is reduced to a great extent.
