汶川大地震时在甘肃省南部山区造成了大量的边坡灾害。本文对调查区公路沿线典型次生边坡灾害的类型、特征及发展趋势进行了研究,同时对一特大型黄土滑坡的现状进行了初步分析。针对调查过程中发现的问题提出了相应的建议。 During the Wenchuan earthquake, a large number of side slope disasters were caused in the mountainous areas of southern Gansu Province. In this paper, the types, characteristics and development trends of typical secondary slope disasters along the highway in the area under investigation are studied, and the status quo of a large loess landslide is analyzed preliminarily. In response to the problems found during the investigation, we put forward corresponding suggestions.
