Description

technical field [0001] The invention belongs to the field of high arch dam construction progress simulation, and specifically relates to a high arch dam construction progress real-time simulation method coupled with temperature field; involves construction progress information and concrete temperature information collection during high arch dam construction period, and temperature field analysis during construction period And a real-time simulation method of construction progress coupled with temperature field. Background technique [0002] Because arch dams have the advantages of strong overload resistance, good seismic performance, and saving construction materials, arch dams are one of the most widely used dam types in high dam construction. High arch dams are usually located in mountainous and canyon areas with complex geological conditions and steep terrain. Due to the complex structure of high arch dams, high ground stress, long construction time span, large amount of ...
