摘要
Abstract
The sand prevention measures, simulated with CFD technology in view of UAE railway engineering background, are calculated and designed to be more realistic. The wind tunnel model and sand fence two-dimensional model are established with GAMBIT and ANSYS software based on the actual situations in UAE. Based on the comparative analysis to select appropriate design parameters, such as particle size of surface coverage, subgrade slope rate, and resistance rate of sand fence, prevention measures are designed. It is concluded that (1) the measures to slow down subgrade slope rate should be adopted, and the suitable slope rate is around 1 : 2 to 1 : 5; (2) the surface on both sides of subgrade should be covered with sand gravel soil, and the particle size should not be less than 5 cm; (3) the height of sand fence should be 1. 5 m with appropriate arrangement according to the resistance rate of 0. 4.关键词
