Method for controlling stress crack at pull rod in concrete engineering

The invention discloses a method for controlling a stress crack at a pull rod in concrete engineering, which is used for controlling the problem that the stress at the pull rod cracks in the process of erecting a formwork by adopting the pull rod in the concrete engineering, and is characterized by comprising the following steps of: S1, establishing a pull rod cracking risk evaluation model of a concrete structure; S2, calculating a cracking risk coefficient according to the pull rod cracking risk evaluation model of the concrete structure; S3, determining a safety coefficient, and performingcomparative analysis on the cracking risk coefficient and the safety coefficient; and S4, processing risk items according to the comparative analysis result. According to the method, a concrete structure opposite-pull rod cracking evaluation model is established, the related opposite-pull rod stress crack cracking risk coefficient is provided, and the cracking risk of each opposite-pull rod is accurately evaluated. 本发明公开了
