新建兰新铁路第二双线路基防风工程的研究

Research on windbreak project for secondary double-track roadbed for newly-built Lanzhou-Urumqi railway

针对兰新第二双线所经大风区的具体情况,在对大风的观测实验研究基础上,通过数值模拟分析、风洞试验等手段,结合列车运营的实际需要,探讨了路基防风工程设计原则和路基防风结构,以确保行车安全。

Aiming at the concrete situation for the wind area in the Lanzhou-Urumqi secondary double-track line, the paper explores the windbreak engineering design, the principle and the windbreak structure of the road bed, based on the observation and experimental research on the wind, by the means of the digital simulation analysis and wind tunnel test, and with the combination with the factual needs of the trains operation, so as to ensure the safety for the travelling.
