Creation optimization method and device for multi-dam model of pumped storage power station

The invention relates to the technical field of pumped storage power station engineering, in particular to a method and a device for establishing and optimizing a multi-dam model of a pumped storage power station, and when a vertical anti-seepage reservoir loading scheme is carried out, only a dam plane arrangement axis needs to be selected, the basic body type of a dam body needs to be specified, and establishment of a dam model is automatically completed at a landform depression; the problems that in the scheme arrangement process of a traditional method, the manual workload is large, the modeling efficiency is low, and engineering characteristic parameters cannot be obtained synchronously during modeling are solved, the dam crest elevation meeting the reservoir capacity requirement is locked through the reservoir capacity difference value, and construction of a dam model is completed through single-time calculation; and main engineering characteristic indexes such as a reservoir capacity curve, main charac
