摘要： 利用低温冻融实验和风洞模拟实验研究古代生土建筑的风蚀机理,结果表明:挟沙风风蚀速率明显大于净风的风蚀速率,其风蚀率是净风的130倍,冻融是风蚀速率增大的一个重要因素,偏西风的降水和风蚀是造成莫高窟古代生土建筑风蚀毁坏的方要原因.实验表明,采取5%LS和10%PS防护材料是防止风蚀的一条重要途径.

Abstract: Through simulating under conditions of low temperatures,freezing and thawing and in wind tunnel,wind erosion mechanism of ancient adobe construction was studied.The results show that erosion rate of wind driven sands is 130 times greater than the winds.Freezing and thawing is also an important factor which causes the in crease of wind erosion.There forewest wind and rainfall are main causes which result in the erosion and destruction of the ancient adobe construction at Mogao Grottoes.Experiment also shows that eroion can be prevented by applying 5%LS and 10%PS conservation materials.

Key words: ancient adobe construction, freezing and thawing, wind erosion
