Dynamic Analysis of Gravity Dam Retaining Section Based on Autobank
The seismic resistance characteristics of gravity dams are an important indicator of dam safety.Taking the retaining dam section of the rockfill concrete gravity dam of Liushugou Reservoir as the analysis object,Autobank finite element calculation software was used to perform static analysis and mode decomposition based on The response spectrum method is used to perform dynamic analysis on it,and the stress results under static load and dynamic load are combined in two ways:"static+dynamic"and"static-dynamic",and the most unfavorable value is compared with the specification requirements.It is found that the stress state of this dam section meets the relevant specification requirements,verifying the rationality of the dam structure design and the safety and reliability of the project.The research can be used as a reference for similar projects.
