摘　　要：微生物矿化沉积在自然界普遍存在，对岩土的固结起着重要作用。利用微生物矿化沉积固化作用在工程中的应用具有成本低、环境友好等特点，引起了广大学者对其机理及应用方面研究的浓厚兴趣。本文介绍了微生物沉积碳酸钙的机理及近年来国内外有关微生物矿化的研究进展，并探讨了其用于放射性尾矿渣胶结固化问题以及微生物矿化沉积固化技术的进一步研究。Microbial mineralization deposition is a common phenomenon in nature, and plays an important role of rock and soil consolidation. Microbial mineralization deposition has attracted many scholars to do research on its mechanism and application because the technology applied in the engineering application is cheap and environmental. This paper introduces the mechanism of calcium carbonate deposited by microorganism and the research progress about microbial mineralization at home and abroad in recent years, and discussing the problem that microbial mineralization deposition is used to the solidification of radioactive tail slag and the further research on the technology of microbial mineralization and deposition.
