ANCHORING BOLTING SYSTEM FOR BRIDGE ABUTMENT AIMING AT STABILIZING CRTS Ⅱ BALLASTLESS TRACK ON BRIDGE

摘要

In the paper, the anchoring bolting system which contains double-column shaped terminal displacement configuration system (TDCS) and inverted T-shaped TDCS for bridge abutment aiming at stabilizing ballastless track on bridge was studied.With the finite element software ANSYS, the longitudinal-vertical-lateral spatial coupling static analysis model is established to study the deformation and force law of the structure.In the model, the interaction between the track slabs and the bed plates, the interaction between the bed plates and the bridge, and the interaction between the bed plates and the anchoring bolting system are all considered.The influence factors, such as the braking force, the temperature force are studied for the both forms of the anchoring bolting system.On that basis, it is easy to find the most suitable anchoring bolting system.
