CRTSⅠ型板式无砟轨道在曲线地段铺设,由于扣件正矢、超高等因素的影响,轨道板上的扣件会丧失一部分调高调距能力。以宁安铁路为例对此进行了计算分析,经分析轨道板在小半径曲线地段扣件调高调距能力丧失较多,对线路今后的运营维修不利,因此建议CRTSⅠ型板式无砟轨道尽量铺设在曲线半径较大的地段。 CRTS Ⅰ plate ballastless track laid in curved sections, due to buckle is the vector, ultra-high factors, the track plate fasteners will lose some ability to adjust the distance. Taking the Ning-An Railway as an example, this paper analyzes and analyzes the loss of ability of the track plate to adjust and adjust the distance of the fasteners in the small radius curve section, which is unfavorable to the future operation and maintenance of the line. Therefore, it is suggested that the CRTSⅠ type slab ballastless track be laid as much as possible In the larger radius of the curve of the lot.
