摘要: 4年防沙实践证明: 莫高窟崖顶防沙试验的工程设计构思是正确的, 设计依据科学可靠, 防护效益显著。对保护石窟和壁画已经起到重要的作用.其具体防护作用是: 1)直接控制偏西风向洞窟搬运沙量的95%左右; 2)洞前夜间积沙减少了80%以上; 3)外围栅栏对来自主风向的外侧积沙的侧导率平均为35%; 对内侧积沙的侧导率, 在偏东风作用下可达57.51%, 在偏西风作用下平均为15.89%.上述防沙作用均具有明显的季节变化。

Abstract: Sand control practices of four years prove that the sand control engineering on the cliff top of Mogao Grottoes is designed based on a correct design and reliable scientific evidence. It has obvious effects to sand control, there are 1) 95 % of sand-transporting quantities from the west of the grottoes are directly controlled ; 2) 80% of accumulated sands in front of the grottoes at night are reduced;3) the average side-diverting-sand capacity outside the fence is 35% to the accumulated sands from main wind direction; inside the fence the figure is 57. 51 % to the eastly wind, and 15. 89% to the westly. The protective effects change with different seasons.

Key words: Mogao Grottoes, Sand control engineering, Side-diverting action
