跨区间无缝线路地段平改立施工安全问题的探讨

Probe into the Safety in the Horizontal-to-vertical Construction of in Cross-section CWR(Continuously Welded Rails)

根据大秦线在跨区间无缝线路地段上进行平改立的实践经验,对施工中是否必须进行应力放散的问题进行理论分析,并提出了施工中应采取的措施。

According to the practical experiences of the horizontal-to-vertical construction in the cross-section CWR on Daqin Line, this paper analyzes theoretically whether or not the stress must be dispersed in construction, and advances some measures that should be adopted in the constructiou.
