Abstract：Karst cracking is currently one of the key geological problems that are of great concern to the world，and it urgently needs to be effectively solved. Microbial mineralization-induced calcium carbonate precipitation（MICP） technology has the advantages of low energy consumption，many types，and environmental friendliness. In recent years，it has been used by many scholars in the research of rock fracture repair. This article mainly elaborates and summarizes the research status of MICP technology in the process of rock fracture repair and the influence of microorganism types and concentration，cementing fluid，construction technology，etc. on the MICP repair effect. At the same time，it also discusses the application of traditional repair materials in karst cracks. The existing problems are also summarized accordingly，in order to promote the practical application of MICP technology in the repair of karst cracks.
