| Abstract: | The insulation treatment to improve the resonant track circuit transmission performance on high-speed railway may lead to poor bond between steel and reinforced concrete. Using fiber steel tendon in ballastless track slab is effective to solve the problem. This paper focuses on the test of ballastless track slab with Basalt Fiber Steel Tendon( referred to as BFST) by means of numerical simulation and static testing. The results show that the results of numerical simulation and test are similar,the model of numerical analysis is reliable, The CRTSII slab reinforced with basalt-fiber-steel-tendon has good ductility,and the bearing capacity meets the requirements. |
