哈尔滨至大连高速铁路设计创新及关键技术回顾

摘要

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.%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。
