研究目的:随着我国西部大开发战略的实施,西北部地区铁路建设步伐进一步加快,有的在沙漠地区通过,分析风沙地区铁路路基设计中应重视的关键环节,提出风沙地区铁路路基选线原则及防护措施,可供同类工程借鉴。研究结论:风沙地区铁路选线,应根据不同的风沙类型确定,并采取有针对性的防护措施。在特殊风沙地区修建铁路,建议采用本体防护及平面防护相结合的防护措施,确保铁路运营安全。
Research purposes: With the implementation of the strategy of western development in our country, the pace of railway construction in the northwestern part of China is further accelerated, and some of them are adopted in desert areas. The key links that should be taken into consideration in the design of railway embankment in the area with windy and dusty sand are analyzed. And protective measures for similar projects for reference. Research conclusions: The route selection of railway in wind-blown sand area should be determined according to different types of sand-blown sand, and take targeted protective measures. It is suggested to adopt the combination of body protection and plane protection to ensure the safety of railway operation.
