微生物矿化技术加固土研究现状综述

Research Status Review of Microbial Induced Carbonate Precipitation Technology in Reinforcing Sand

微生物矿化技术简称为MICP技术,是近年来发展起来的新兴技术。通过查阅国内外相关文献,系统地总结和分析了微生物矿化的作用机理以及国内外学者对矿化作用的研究情况。介绍了常见的用于处理不良地基土的微生物种类及其反应原理,调查了微生物在发生矿化作用过程中的影响因素以及经微生物矿化技术加固后土体最终力学性能测试的总结,并提出了研究建议。

MICP technology is the abbreviation of the Microbial induced carbonate precipitation.It has been developed in recent years.Through looking up related domestic and foreign documents,this paper systematically summarizes the mechanism of microbial induced carbonate precipitation and the progress of mineralization researches in domestic and foreign scholars.This paper also introduces the common microbial species and their working principle for the reinforcement of soils which have not reach the standard,investigates the influencing factors of microorganisms in the process of mineralization and the final mechanical properties of soil after microbial mineralization and puts forward research proposals.
