| Abstract: | The wind-resistant technology is a key factor in the construction and operation of the Second Double Line of Lanzhou-Urumqi Railway. Based on a series of researches, the characteristics of wind environment along the line are confirmed and the criterions for safe operation and speed of high speed train under hard wind are established. In combination with researches for wind-resistance on subgrade, bridge, wind-resistant open tunnel, catenary system and early warning system for strong wind, the main design criterions and the type of structure for wind resistant technology for the construction of this railway. The researches on wind-resistant technologies have provide guarantee and support for design and construction of railway project in wind area. |
