珊瑚礁是一类特殊的工程建设场地，受地质成因、生物作用、海洋水动力环境和地质环境演化等多方面影响。开展珊瑚礁场地工程地质分区研究，不仅对认识珊瑚礁岩土层的成因和变化规律、分析评价珊瑚礁场地的工程地质条件等具有重要的理论意义，而且对未来南海岛礁工程建设具有重要指导作用。在现场地质调查的基础上，采用现场原位测试、室内试验和钻探岩芯分析等综合技术手段，分析了三亚珊瑚礁地层的演化历史，对地层结构特征、矿物成分、化学成分和土层物理力学性质进行了深入分析，将三亚海岸珊瑚礁场地划分为泻湖沉积区、砂坝堆积区和水下珊瑚生长堆积区；对各工程地质分区的工程特性和建设适宜性进行了分析评价。研究成果可以对珊瑚礁场地的地质调查、工程规划和设计提供指导和借鉴。

Coral reef is a special engineering construction site, which is influenced by geological origin, biological effects, marine hydrodynamic and geological environment, etc. The research on engineering geological division is not only important in understanding and evaluating the engineering properties of coral reef deposits, but also has important guidance on coral reef engineering design and construction. Based on field geological survey, in-situ tests, drilling and a large number of laboratory experiments, analyses are conducted for geological origin of coral reef stratum, landform, stratigraphic configuration, mineral and chemical composition, and physico-mechanical properties of coral reef sediments. It is concluded that coral reef in the coast of Sanya can be divided into lagoon depositional area, sandbar area and underwater live corals accumulation area. Finally, evaluation is carried out for the engineering characteristics of each division, and suitability of construction is analyzed. The results have important guidance for geological survey of coral reef and engineering planning & design.
