摘要
本文应用1986年11月5日美国陆地卫星5号TM资料所处理的卫星像片,对山东灵山岛地质构造及边坡稳定性进行了分析判译。发现,该岛岩性脆弱、地质构造十分复杂、地势陡峻,山体边坡动力地质作用强烈;经实地考察,证实了解译结果与实际情况基本吻合;同时指出了岛上边坡不稳定地区的分布规律,可供开发和建设海岛参考。
Investigation on geological structure and stability of mountain slopes of Lingshan Island with TM image.Satellite image shows that the island has a straight shoreline in the west and a crooked shoreline in the east. On the north and east of the Island, there are some islets and reefs. The strata in the island are mainly that of detrital rocks (J3l), volcaaic rocks, (K1g) and marine deposits (Q4m). There are many faults, vertical joints in the island. The island's geological structural lines are mainly in the direction of NNE, EW, SN, NW and it's geological gravitation is active, which makes the mountain slopes unstable and liable to landslide and collapse.
