Abstract: In order to improve the application effect of concrete high arch dam construction simulation and provide useful reference for software development and engineering application in this field, aiming at the lack of standards for selection and evaluation of priority pouring rules during high arch dam pouring construction simulation, on the basis of in-depth study of the factors affecting the priority pouring rules, we present the types of priority pouring rules commonly used during the construction simulation of high concrete arch dams, such as balanced rise-minimum block priority pouring rules, special part priority rules, old concrete priority pouring rules, bank slope dam section priority pouring rules, odd or even dam section priority rules, other priority rules.And we propose the evaluation indexes for priority rule selection, such as pouring progress and key control node progress such as flood season node, pouring progress appearance, concrete monthly pouring strength distribution, old concrete production.An example analysis of the high arch dam of Zhongyu Hydropower Station was carried out, which confirms the rationality of the proposed priority pouring rule type and evaluation indexes.The relevant results can be used for reference in concrete pouring construction of similar projects.
