Ballastless track statics model considering plastic damage

The ballastless track statics model considering the plastic damage comprises a base plate, grooves are formed in the upper surface of the base plate, the base plate is transversely and sequentially arranged, the bottom of self-compacting concrete is attached to the grooves of the base plate, and the grooves of the base plate are filled with the self-compacting concrete; prestressed track plates are uniformly arranged on the upper surface of the self-compacting concrete, fasteners are arranged on the side walls of the steel rails, and the steel rails are fixedly connected with the prestressed track plates through the fasteners. A more accurate and reliable basis is provided for design and construction of the ballastless track, key information such as stress distribution and deformation conditions of the ballastless track under the plastic damage condition and stress conditions of overhead line system suspension can be obtained through simulation testing of the model, and therefore the performance and stability
