中文摘要：

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.

英文摘要：

Research of coral reef is one of the important ways to track globe change. Its development also fits the demand of coral reef engineering in recent years. Corel reef is a special type of rock soil developing in tropical ocean environment. The coral reef area in the southwestern Leizhou Peninsula is special not only because of its component but also because of its de- veJopment. In this area, the intensity of hydrodynamic force is different in different parts of coral reef, which is the main rea- son that makes the ecological environment and deposition to be zonal. It combines the coral reef physiognomy and engineering geology property; these factors form different rock mass structure and engineering geology belt. In this study, we analyze the geology, environment, rock mass structure and engineering geology of this area. We then estimate the ground suitability of coral reef area so that our study can provide guidance for resource exploitations.
