| Abstract: | It is a rare phenomenon that wind erosion induces slope instability, especially in the multivariate layered steep soil slope in the Jiaohe ancient city mesa in Turpan, where discontinuous medium sands and fine sands layers exert the vacuum and cause transformation and destruction due to different wind erosion effects. So the slope was chosen as a typical case. According to the environmental characteristics and the evaluative history, this paper adopted the qualitative analysis of geologic history conglobati... |
