摘　　要：结合梁端钢轨超限支承间距情况,提出采用道床板悬出、抬枕装置、跨梁缝短梁等措施,有效解决了梁端钢轨支承间距超限的工程难题,确保了梁端无砟轨道钢轨支承间距满足要求。Combining with the beam end limit rail bearing spacing, this paper put forward using rail bed board hanging, pillow lifting device, cross beam joint short beams and other measures, effectively solved the engineering problems of beam end limit rail bearing spacing, ensured that the beam end ballast-less track spacing met the bearing requirements.
