风雪病害的数值模拟仿真

Numerical Simulation of Wind and Snow Damage

针对新疆北疆地区高速公路风雪灾害给交通安全带来严重危害这一情况,采用fluent软件计算机数值仿真模拟方法对填方路基,挖方路基,半填半挖路基断面,敞开式路基断面形式进行模拟试验。模拟结果表明:数值仿真模拟试验结果与过去已知回避风雪病害的结论接近,与现场实际风场情况较为接近,软件模拟可信度较高。

In order to deal with the problems of snow disaster bringing serious harm to traffic safety of highway in the Northern Xinj iang area,fill subgrade,cut subgrade,half-filled and half-dug subgrade and open type subgrade are simulated with the method of fluent software computer numerical simulation.Results show that the numerical simulation results are close to both the known conclusion of avoiding snow disaster and the condition of actual wind field.The software simulation has high reliability.
