The invention discloses a BIM-based mud-water balancing shield slurry parameter management system being developed based on the BIM in a computer. The slurry parameter management system comprises a geological parameter module, a design calculation module, a parameter suggestion module and a construction parameter module that are connected successively. A mud-water balancing shield slurry parameterinformatization design is realized; a mud-water balancing slurry parameter storage base is established; and a comparison function of similar engineering project design parameters is realized. With selection of the mud-water balancing slurry parameters, visual management from designing to final technical solution determination is realized; and digitalization and informatization management for the mud-water balancing shield is realized.
