In order to explore the longitudinal and lateral resistance mechanism, contribution and influence of steel rod depth and shoulder width of steel rod reinforced sleeper, and to provide a new method for increasing resilience and stability of the long sharp slope in Sichuan−Tibet railway, a series of longitudinal and lateral resistance tests were carried out. Firstly, the overall characteristics and contribution of the longitudinal and lateral resistance of the steel rod reinforced sleeper were obtained. Then, by changing steel rod depth and shoulder width, the influence of them on the longitudinal and lateral resistance of the steel rod reinforced sleeper was explored. The results show that, compared with ordinary sleepers, the longitudinal and lateral resistance of steel rod reinforced sleeper has increased. With the shoulder with of 500 mm, shoulder height of 0 and insertion depth of 400 mm, the lateral resistance of steel rod reinforced sleeper is 53.7% higher than that of ordinary sleepers with shoulder width of 500 mm and pile height of 150 mm, and longitudinal resistance is 39.2% higher. At the same time, the contribution of sleeper bottom in lateral resistance is 8% higher compared with ordinary sleepers, with 26% higher in longitudinal resistance. The insertion depth of the steel rod exerts a great influence on the resistance. For instance, with shoulder width of 500 mm and shoulder height of 0, when insertion depth changes from 100 mm to 400 mm, the increment of longitudinal is from 5.1% to 39.2%, and that of lateral resistance is from 6.1% to 53.7%, compared with ordinary sleepers with shoulder width of 500 mm and shoulder height of 150 mm. With the change of the shoulder width, the longitudinal resistance changes slightly and the lateral resistance changes more.
