天然胶结钙质土是广泛分布于热带及亚热带海洋中由生物碎屑经碳酸钙胶结或固结而形成的碳酸盐岩类。其独特的工程性质常常给岩土工程设计与施工带来麻烦，也正因此引起了研究者的兴趣并对其开展了较为全面的试验研究工作。针对天然胶结钙质土、人工胶结钙质土的室内试验以及人工胶结钙质土试样的制备等3方面取得的研究进展进行总结回顾，汇总了胶结钙质土的基本应力-应变行为以及围压、初始密度及胶结度等主要参数的影响规律，指出了研究中尚存在的问题，并对胶结钙质土的进一步的研究工作进行了展望。该工作必将对此领域的研究具有借鉴和指导意义。

The naturally cemented calcareous soil is a carbonate soil or rock cemented by high-magnesium calcite or aragonite. It usually contains a large portion of coral and other tropical marine organism. Its unique engineering properties often result in troubles and difficulties in the geotechnical design and foundation construction. Its characteristics also attract research and experimental interests of many researchers. This paper presents state-of-the-art review of developments of the laboratory tests on both naturally and artificially cemented calcareous soils as well as the sample preparation techniques of artificially cemented soils. The general stress-strain behaviors of the cemented calcareous samples and factors that might affect its characteristics, such as confining pressure, initial sample density, and degree of cementation, are also summarized. The research work that could be improved is also proposed with an objective of providing a research guideline for the further studies of cemented calcareous soils.
