既有线板式橡胶支座横向限位器的研制

Study on the Transverse Restrainers of the Plate Type Elastometric Pad Bearings in Existing Railway

分析既有线提速引起桥梁横向振幅增大的原因,在此基础上研制既有线板式橡胶支座横向限位器,详细介绍其材料参数和施工工艺,为列车提速创造安全条件,供既有线改造设计提供参考。

In this paper, the factors which cause the enhancement of the bridge amplitude in existing railway are analyzed. Based on the results, the transverse restrainers of the plate type elastometric pad bearings is developed, the materials and construction technology of it are introduced. The safety of existing railway in the high speed condition can be controlled by using the transverse restrainers. This provides a reference for the reconstruction of existing railway.
