Research On The Durability Of The Maglev RC Beam

Maglev train is a high-tech and modern traffic instrument with many advantages such as fast, safe, comfortable, economical, green and low-consume. But it's brand new and has not been widely used, so the research about it is not very perfect.Especially the research on the durability of the maglev RC beam is blank. The influence on the durability of the maglev RC beam of the carbonation and stray-current is analyzed in detail based on the achievement of the present research in this article. The durability of the maglev RC beam is evaluated on the method of the fuzzy various attribute decision-making theory combining the influence of carbonation, stray-current and chloride. And the suggestion of the equal durability section design is put forward.1. Using the formula of speculating the carbonation processes in the prestressed concrete which is gotten from the experiment results and FEM program speculate the carbonation processes of the maglev RC beam.2. Prognosticate the service life of the maglev RC beam under the stray-current consulting the date of the stray-current in the subway and the experiment results of the relationship between the water-cement ratio and the resistance of the concrete.3. Point out the best project on the durability of the concrete considering the influence of the carbonation, stray-current and chloride using the fuzzy various attribute decision-making theory.4. Put forward the suggestion of the equal durability section design thinking over the influence on the carbonation of the wind.
