宁夏须弥山窟区风环境被动调节技术研究

Research on the Passive Improvement Technology of the Wind Environment in Xumi Grottoes in Ningxia

文章以营造有利于石窟保护的物理环境为基础,研究了设置防风林带的被动优化调节设计对窟前风环境的影响。通过数值模拟方式证明设置防风林带的被动优化调节设计,对主害风向风速减小1.0m/s,极大地改善了窟前风环境状况,从而达到了减弱风化强度保护文物的目的。

This paper is based on creating a physical environment conducive to the protection of grottoes. The influence of the design on the wind environment before the cave can be identified on the passive optimization adjustment of the forest belt. By means of numerical simulation, it is proved that the passively optimized regulation design of the forest belt reduces the main damaged wind speed by 1 .Ore/s, which greatly improves the situation of the wind environment before the cave, thereby achieving the purpose of protecting the cultural relics from weakening the erosion.
