摘要：自青藏铁路格尔木-拉萨段(简称格拉段)修建伊始,沙害问题就是危害铁路正常运营的一个不容忽视的问题,而对于高寒风沙活动规律及其防治等科学问题亟待研究.通过近年来持续对青藏铁路格拉段风沙环境及防沙工程的系统研究,本文分析了青藏铁路格拉段风沙危害特征,提出了防治思路与防护体系配置,进而分析了工程实施后的防护效益.通过对青藏铁路风沙灾害特征及其防治的系统总结,填补了高寒区风沙危害防治研究的盲区,更为青藏高原及类似地区铁路工程的风沙危害防治提供科学依据和技术支撑.
Since the beginning of the construction of the Golmud to Lhasa section of the Qinghai-Tibet Railway,sand damage has been a serious problem that cannot be ignored because it threatens the normal operation of the railway.Thus,alpine blown sand activity and its prevention and control must be studied urgently.Through continuous,systematic research on the blown sand environment and sand control engineering of the Golmud to Lhasa section of the Qinghai-Tibet Railway in recent years,we analyzed the characteristics of the blown sand hazards,proposed prevention and control concepts and a protection system configuration,and analyzed the protection benefits after the project was implemented.In this paper,the characteristics of a blown sand disaster and its prevention and control are summarized systematically,which fills the research gaps in terms of blown sand hazards in high altitude and cold regions,and provides a scientific basis and technical support for the prevention and control of blown sand hazards of railway projects in the Qinghai-Tibet Plateau and similar regions.
