In the building of many large concrete dams across the country. Significant dam cracking can have major environmental, economic and is ocialic on sequences. Collapse of high concrete dam may cause serious harm to economic development as well as safety of the people thereby necessitating the need for research on safety and stability of high concrete dam under high water and seismic conditions.In this project, the concrete gravity dam of Koynai was used as an example,using the ABAQUS program based on the extended finite element method to analyze the Koyna dam under static and dynamic conditions which has been common used for the study of crack growth. An analytical prediction of crack propagation in concrete gravity dams is ipresented.The two dimensional seismic numerical study was done using acceleration-time records from Koynai earthquake in1976 dam concrete cracking range and cracking were discussed during a seismic time. The locations that are easy to generate cracks are iillustrated from the analysis and the findings showed that, during seismic activity the Koyna dam was rather unsafe. Also, the parametric study of Koyna dam has been studied by apply earthquake from down stream side. The findings of parametric study showed that, the effct of down stream side is maximum. Therefore, the results of the work can provide a valuale guide for the design and operation of the dam system
