莫高窟顶尼纶网栅栏防沙效应初步研究

莫高窟顶风沙灾害严重,多年来,一直未能有效地阻止流沙的危害。作者通过现场风沙观测,基本摸清了风沙危害的方式,并因害设立了“A字型”的防沙体系。首次采用尼纶网作为栅栏材料,经过两个风季效益观测,效果较好。本项目的研究为尼纶网栅栏的运用提供一条新途径。

Experimental Research of Nylon Fence off Sand on Roof of Dun Huang Mogao Cave

The blown-sand damage to Mogao Cave roof is severe. Over a number of years, the harm of shifting-sand cann't be effective prevented as ever. In 1989,Dun Huang Acace-my in cooperation with Institute of Desert Research,Chinese Academy of Science and Getty Conservation Institute develop test research to preventing blown-sand disaster by nylon net. It sets up 'A' form of preventing blown-sand system, Which based on the rule of blown-sand damage on roof of Mogao Cave. In comparative observation to two windy seasons and Tummel simulation test research,pattern of accumulative sand in relation to windspeed out lines establish in front to back of the fence preliminarily. It is that evaluates functions of the fence in preventing blown-sand.obstructing sand and leading sand. In this paper, author would suggest that new opinion how effects a radical control shifting-sand at Dun Huang Mogao Cave roof.
