摘要
为了推动微生物诱导碳酸盐沉淀(MICP)技术在裂隙岩体加固中的工程应用,介绍了该技术的主要影响因素,归纳分析典型应用实例,探讨当前面临的技术挑战.MICP技术在提高裂隙岩体强度与降低渗透性方面表现显著,其加固效果受注浆溶液、环境条件、裂隙特征及注浆工艺等因素共同影响.结合当前研究,总结了MICP技术在二氧化碳地质封存、尾矿治理、石质文物保护及石油开采等领域的应用现状,讨论了该技术在沉积均匀性、长期稳定性和经济性方面的挑战.未来的研究应结合室内与现场试验,优化菌株性能与注浆工艺,降低成本,并开发精确的多场耦合模型,以推动MICP技术在复杂地质条件下的实际应用.
The key influencing factors were introduced,representative application cases were analyzed,and current technical challenges were discussed in order to promote the engineering application of microbially induced carbonate precipitation(MICP)for reinforcing fractured rock masses.MICP proved effective in enhancing rock strength and reducing permeability,with its performance influenced by factors such as grouting solution composition,environmental conditions,fracture characteristics,and grouting procedures.The application of MICP in CO2 geological sequestration,mine tailings remediation,stone heritage preservation,and petroleum extraction was reviewed based on recent research,while identifying challenges related to deposition uniformity,long-term stability,and economic feasibility.Future research should integrate laboratory and field experiments,optimize microbial strain performance and grouting strategies,reduce costs,and develop accurate multi-physics coupling models in order to enable practical implementation under complex geological conditions.
