  Abstract：Research purposes： This article studies the structure design of 1 667 mm broad gauge sleeper based on the American code, according to the basic parameter and ordain, puts forward the design principle of the sleeper. Based on the America AREMA calculation method, this article analyses the bending moment for sleeper, the calculation of bearing capacity of rail seat and sleeper center section, the calculation of static load test and so on, provides the basis for the test for sleeper and determines the basic design method of the broad gauge sleeper meeting the requirements of American Standard.Research conclusions：(1) The size and amount of reinforcement of the designed broad gauge sleeper meet the requirements of technical requirement. (2) According to the calculation method of America code, put forward the bearing capacity and static load test of sleeper. (3) The calculation results show that the sleeper bearing bending moment is greater than the load bending moment. (4) Static load and fatigue tests show that the designed sleepers meet the tests and anti-fatigue requirements. (5) Calculation and tests indicate that the broad gauge sleeper meet the standard based on AREMA and the requirements of Argentina railway project.
