| Simulation analysis of pulse wind loading induced by 380 km/h high speed train |
| 摘要 |
| 針對(duì)高速鐵路聲屏障的高速列車脈動(dòng)風(fēng)荷載問題，介紹既有研究資料，并進(jìn)行高速列車以350 km/h，380 km/h的速度通行聲屏障區(qū)域的CFD計(jì)算分析。結(jié)果表明，350 km/h速度下最大風(fēng)壓力為1 474 Pa，380 km/h速度下最大風(fēng)壓力為1 707 Pa。聲屏障底部承受的風(fēng)荷載最大，并沿高度向上先 |
