崩塌区位于大渡河右岸,冰水堆积及河流侵蚀低山地貌区.崩塌区斜坡地带多被灌木、乔木覆盖,为单面坡,局部呈凹腔负地形.通过对沙坪镇羊竹坝崩塌工程地质条件的研究及对该区边坡稳定性进行评价,认为边坡整体稳定性较好,但应注意长期表层土层垮塌形成危石带来的危害.因此应对崩塌区地质灾害进行治理.

The Yangzhuba breakdown in Ebian is located at the right bank of the Dadu River, lying in a fluvioglacial deposit and stream-eroded low hills. The breakdown slope is a monoclinal slope overlain by shrubbery and high forest. This article deals with engineering geological conditions and slope stability evaluation of the Yangzhuba breakdown. Its stability is better, but should pay attention to long-term soil collapse hazard risk.
