| 摘 要： | 吐鲁番交河故城台地高陡层状土质边坡的失稳过程受风蚀控制和影响非常典型;在土层组合特征和抗风蚀能力差异以及当地终年多大风的气候特征的共同作用下,坡体土层形成风蚀空腔并在空腔的控制下发生变形破坏.以工程地质定性分析、风洞实验、物理模拟为主要手段,结合数值模拟,分析了该边坡在自然风蚀改造过程中表现出具有特殊性、多样性和阶段性...

| Abstract: | It is very typical that wind erosion controls and influences the instability process of steep slope comprising layered soils at the mesa of Jiaohe Ruins in Turpan.Wind erosion caverns can be formed in the layered slope soils.They can further cause the slope to deform and failure.They are typically formed in the slopes with low anti-wind erosion capacity and together with the local climate characteristic of frequent gales.The paper employs the methods of engineering geology,experiment of wind tunnel,physical... |
