青藏铁路格拉段风动力环境及其对铁路沙害的影响

doi:10.7522/j.issn.1000-694X.2015.00272

摘要/Abstract

摘要： 以青藏铁路格拉段沿线主要气象站点1955—2014年的气象数据及部分野外观测数据为基础，从风向、大风沙尘暴日数、输沙势和年均风速变化等方面阐述了青藏铁路格拉段风动力环境特征，并揭示了其对铁路沙害的影响。格拉段铁路沿线风向单一、风能环境较高、铁路沙害可能进一步发展。本研究在青藏铁路沙害监测和防沙体系完善方面具有指导意义，同时也为其他沙区公路、铁路防沙设计提供借鉴。

Abstract: Based on the meteorological station statistical data from 1955 to 2014 and field observation data along Gerlha section of the Qinghai-Tibet Railway, this paper studied the characteristics of wind energy environments in terms of wind direction, gale days and sand-dust storm days, sand drift potential and decadal variations of annual mean wind speed, and demonstrated their impacts to railway sand hazards. Mono wind direction, relatively high wind energy environments and the sand hazards going worse were our conclusion. This research has important meaning in monitoring the sand hazards developing trends and improving sand control system along Qinghai-Tibet Railway. It also can be a good reference for the design of other highway and railway sand control system which pass sandy regions as well.

Key words: Qinghai-Tibet Railway, sand hazards, wind energy environments
