摘要
本研究采用铜王公路2#滑坡侵蚀实例,定性分析了该滑坡侵蚀的诱发因素、变形特征、复活的原因;并在研究该滑坡侵蚀地貌特征、岩土体组成、水文地质特征后,建立了地质模型和计算模型;采用弹塑性有限元法对斜坡的初始应力场特征进行模拟研究。计算成果及分析表明,铜王公路2#滑坡处于非稳定状态。最后,对该滑坡滑动后可能造成的灾害程度及侵蚀量进行评估。
Taking No.2 landslide erosion of Tongwang highway as an example, the inducing factor, deformation behavior and the cause of the landslide revival are analyzed qualitatively. After the researching on the geomorphic character, rock - soil body compositions, hydrological character, the geological and calculating model is established. Then, the initial stress field of the slope is simulated by means of elastic - plastic finite element. The result shows that the Tongwang highway is under a unstable condition.Finally, the possible disaster degree and erosion amount after it＇s sliding are evaluated.
