珊瑚礁是全球气候变化研究的主要内容之一,近年来为适应珊瑚岛礁工程建设的需求,珊瑚礁研究得到较快发展。珊瑚礁是发育于热带海洋环境中由生物作用和地质作用共同形成的地质体,是一种特殊的岩土介质类型。雷州半岛西南部珊瑚礁区无论在其物质组成还是发育环境上都具有独特性,该区海洋水动力作用在珊瑚礁体不同部位强度不同,具有明显的分带性,是造礁珊瑚生态环境和碎屑沉积分带的主要原因,它与珊瑚礁地貌分带、珊瑚礁工程性质相结合,形成了珊瑚礁不同的岩体结构和工程地质分带。在分析了该区地质背景、岩体结构和工程地质分带等的基础上,对雷州半岛西南部珊瑚礁区场地稳定性进行探讨,为该区工程建设提供依据。
Coral reefs are one of the major contents of the research on global climate change. In recent years, the coral reef research has been developed rapidly to meet the needs of coral reef construction. Coral reefs are geologic bodies formed by both biological action and geological action in the tropical marine environment. They are a special type of geotechnical media. The coral reef areas in the southwest of Leizhou Peninsula are unique in both their physical composition and developmental environment. The marine hydrodynamic effects of this area are different in different parts of the coral reefs and have obvious zonation. They are the reef ecological environment and debris The main reason for the zonation of sediments is that it combines with the geomorphological features of the coral reefs and the nature of the coral reefs to form different rock mass structures and engineering geological zonation of coral reefs. Based on the analysis of the geological background, rock mass structure and engineering geological zonation, the stability of the coral reef area in the southwestern Leizhou Peninsula is discussed, which provides the basis for the project construction in this area.
