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。
Natural cements Calcareous soils are carbonate rocks that are widely distributed in tropical and subtropical oceans and are formed by cementation or consolidation of biological clays with calcium carbonate. Due to its unique engineering properties, it often brings trouble to the design and construction of geotechnical engineering. As a result, it has aroused the interest of researchers and carried out a more comprehensive experimental research on it. In this paper, the progress of the research on the natural cemented calcareous soil, the artificial cemented calcareous soil and the preparation of the artificial cemented calcareous soil were summarized and reviewed. The basic stress-strain behavior of the cemented calcareous soil, Pressure, initial density and degree of cementing on the main parameters of the study, and pointed out the existing problems in the study, and further research on the cemented calcareous soil was prospected. This work will certainly be of reference and guidance to the research in this field.
