黄土-基岩不整合面与滑坡的关系

Relations between Loess-bedrock Unconformity Surface and Landslide

不整合面属于原生的软弱结构面，黄土-基岩不整合面与黄土地区普遍发育的滑坡现象关系密切，逐渐引起学术界的关注。通过对已有不整合面以及黄土滑坡相关的研究成果进行综述，提出了不整合面与黄土滑坡关系研究中存在的问题以及今后的研究方向：1）黄土-基岩不整合面的分类问题；2）黄土-基岩滑坡的分类问题；3）不同类型黄土-基岩不整合空间结构及风化壳发育特征；4）不整合面展布特征与滑坡空间发育规律之间的相关性；5）不整合面产状、形态及结构特征对黄土斜坡稳定性的影响。进一步分析不整合面这一重要地质界面在黄土-基岩滑坡中的作用规律，丰富黄土滑坡形成机理的理论。

As originally weak texture plane, loess-bedrock unconformity surface is closely related to landslides developed seriously in loess areas, which has gradually attracted the attention of academics. By summarizing the interrelated literatures of loess-bedrock unconformity surface and landslide, we proposed some issues and future research fields： 1） to classify loess-bedrock unconformity surface; 2） to classify loess-bedrock landslide; 3） to research the structure and weathered crust characteristics of different types of loess-bedrock unconformity surfaces; 4） to research the spatial distribution of loess-bedrock unconformity surfaces and the correlation with landslides; 5） to research the impact of occurrence, morphology and structural characteristics of unconformity surfaces on loess slope stability, then to make further exploration on the action laws that unconformity surfaces, an important geological interface governs loess-bedrock landslides, so as to enrich the theory of formation mechanism of loess-bedrock landslides.
