Study on the Design Method of Prestressed Concrete Sleeper Based on Chinese and American Criteria

Abstract:

For the design of prestressed concrete sleeper, design methods and standards in different countries are different. America and China design sleeper by the allowable stress method, UIC design by probability limit design method. China has design II-sleeper by the method of reliability, but the theory is not immature so that II-sleeper appeared a lot of cracking problem. In recent years, designing IIIa-sleeper still use the allowable stress method. By contrast of process of designing IIIa-sleeper in China and America, include design load moment, the prestress loss, bearing capacity of structure, test and so on. Get the main difference of designing sleeper in China and America, and the rationality and practicability of different design method.
