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,有着独特的工程环境特性和工程地质性质。珊瑚礁工程地质研究是现代工程地质学的一个新课题,是近年来为适应珊瑚岛礁工程建设的需求而发展起来的。介绍了珊瑚礁工程地质研究的内容及意义,综述了国内外珊瑚礁工程地质研究的历史现状及其进展,指出应将珊瑚礁体作为工程岩体,进行工程地质环境区带划分及各区带工程地质条件评价;分析礁岩体结构特征和礁体稳定性及其影响因素;分析礁体工程适宜性、地基及其环境与工程活动相互关系。针对珊瑚礁岩土的土力学特点,加强珊瑚礁颗粒破碎机理及其对工程地质性质影响机制的研究;建立能够代表珊瑚礁应力—应变特性的本构关系。

Coral reef is a special type of rock soil developing in tropical ocean and has typical engineering properties. As a new research field of modern engineering geology,coral reef engineering geology study is developing under the necessity of coral reef construction and has strategic significance and great application.With the development of ocean resources,coral reefs are becoming more and more important.The types and dimensions of coral reef construction urge us to make deep research on coral reef engineering properties.This paper introduces the concept and modern distribution region of coral reefs,and the contents and significance of coral reef engineering geology research.The authors comprehensively discuss the research history,situation and progresses of coral reef engineering geology in home and abroad. We also point out that we should strengthen the research of particle crushing mechanism and constitutive model of coral reef.Taking coral reef as engineering rock-mass the emphases of coral reef engineering geology research should be put on reef-mass structure and stability,engineering geologic zone and engineering suitability,and relationship between coral reef environment and engineering action.

Key words: Coral reef, Engineering geology, Division of zone, Reef-mass structure.
