Abstract

Abstract

The Lingshan Island is a small island located in the nearshore area of the Yellow Sea to the south of Huangdao District of Qingdao City, Shandong Province. It is tectonically belonging to the Sulu orogenic belt. The island is dominated by Early Cretaceous complex rocks of deep-sea facies, and a large number of soft sediment deformation phenomena have been observed. This paper focuses on the genetic mechanism of geological disasters at the Lingshan Island Provincial Nature Reserve, and summarized are the collapse features and their evaluation method. Risk assessment suggests that the risk of Laohuzui collapse on the Island is moderate, while the risk at the Tangquan Village is small. The evaluation method used in this paper may provide a reference for similar projects.
