    GENETIC MECHANISMS OF THE COLLAPSING GEOHAZARD ON THE LINGSHAN ISLAND AND THEIR RISK ASSESSMENT

    • 摘要: 灵山岛是山东省青岛市西海岸新区南部黄海近岸海域中的一个小岛,位于苏鲁造山带内,岛上最典型地层为早白垩世深海相复理石,发育了大量软沉积物变形现象。分析了灵山岛省级自然保护区地质灾害成因机理,总结了其坍塌特征及评价方法,划分其崩塌地质灾害等级,最终对研究区进行危险性评价。研究发现,灵山岛老虎嘴崩塌威胁危害程度为中等,灵山岛唐泉村崩塌威胁危害程度为小型,可为后续类似工程提供参考。

       

      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.
