敦煌莫高窟岩体风蚀机理及其防护对策的研究

摘要/Abstract

摘要： 利用风洞模拟实验研究莫高窟岩体的风蚀机理,结果表明,挟沙风风蚀速率明显大于净风。沙岩(层)结构、构造脆弱是产生岩体风蚀差异的主要原因。其中"沙楔"作用加速了风蚀烈度。采用10%的SS和10%的PS材料加固岩体是防止岩体风蚀的一条重要途径。

Abstract: A simulation expriment on the deflation mecharrism of the Mogao Grotto rock body was conducted in the wind tunnel.The results showed that the deflation rates of sand-carring winds are significantly higher than these of clean winds,the weak stratified structute of the conglomerate redk is the ftincipal factor respeible for the deflation differences;and the "sand-wadge" action strengthens the intensity of the deflation.Applieation 10% SS and 10% PS to reinforce the rock body is an effective ways to halt the deflation.

Key words: Dunhuang Grottoes, Deflation, Rock bydy protective material
