哈尔滨至大连高速铁路设计创新及关键技术回顾

Design Innovation and Key Technology Review of Harbin to Dalian High-speed Railway

对哈尔滨至大连高速铁路的设计创新及关键技术进行回顾总结,系统阐述在路基防冻胀技术、大跨度桥梁结构设计、接触网融冰技术、道岔融冰除雪等方面的研究创新及成功应用,以哈大高速铁路设计为依托,形成完整的、系统的高纬度严寒地区修建高速铁路的修建技术。

This paper reviews the design innovation and key technology of Harbin-Dalian High-speed Railway, and systematically describes the innovation and successful application of subgrade frost-heaving technology, structural design of large span bridge, catenary ice-melting technology, and turnout snow-removing and ice-melting technology. A complete and systematic theory for high-speed railway construction in regions of high latitude and severe cold is established based on the summary of Harbin- Dalian High-speed Railway design.
