铁路工程风吹雪监测方法研究

Research on Monitoring Method of Snow Drifting Disaster in Railway Engineering

风吹雪作为新建克拉玛依至塔城铁路工程的主要自然灾害,其防护是一项世界性的技术难题。铁路与主导风向的夹角、风速、路堤高度、边坡率、路堑形式、路堑深度及路堑坡率等因素都是影响铁路风吹雪的直接因素。铁路工程风吹雪灾害的成因复杂,仅通过理论分析难以准确评估其危害程度,通过建立连续3个冬季的监测周期,详细介绍了以自动监测为主、人工监测为辅的监测方法。基于各项现场基础监测资料,通过研究分析获得一系列成果,为现场各工点制定行之有效的防护措施提供技术保障,同时为进一步攻克风吹雪灾害防治的技术难题提供数据支持。

Snow drifting disaster is the main natural disaster of the new Karamay-Tacheng railway project. At the same time, its protection is also a worldwide technical problem. From the analysis of factors affecting the wind and snow drifting disaster in railway construction, factors such as the angle of wind direction, wind speed, embankment height, slope rate, cutting type, cutting depth, and road slope rate are the direct factors that affect the snow drifting disaster in railway. In view of the complexity of the snow drifting disaster in railway engineering, it is difficult to accurately grasp the degree of damage through theoretical analysis. This paper establishes three consecutive winter monitoring cycles, introduces the monitoring methods based on automatic monitoring and supplemented by manual monitoring, monitors the basic data on the scene, studies and analyzes the main conclusions. It provide technical support for the effective protection measures in the field,and also provide data support for further overcoming the technical difficulties in the prevention and control of snow drifting disaster.
