The invention discloses a creep-considered constrained concrete free-form surface form creation method, and aims to solve the problem that an obtained structure is unreasonable due to the fact that concrete creep is not considered in the form creation process at present. The invention provides a creep-considered constrained concrete free-form surface form creation method. The method is simple andeffective, the influence of concrete creep under long-term load can be considered, and the safety of the structure is ensured.
