NOVELTY - Use of graphene oxide for improving soil consolidation strength, is claimed. USE - The graphene oxide is useful for improving soil consolidation strength (claimed). ADVANTAGE - The graphene oxide: enables microorganisms to induce rapid growth of calcium carbonate crystals in calcium carbonate thus increases the yield of calcium carbonate; changes the size of the calcium carbonate crystals which is conducive to the consolidation of the soil; and improves the compressive strength of the soil. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) composition for improving soil consolidation strength, comprises urease microorganism solution, graphene oxide solution and consolidating fluids, where viable count of the urease-producing microorganism in the urease-producing microorganism solution is 1-9x 107 cfu/ml, concentration of the graphene oxide solution is 5-20 mg/l and consolidating fluids is 0.3-0.5 mol/l and volume ratio of the urease-producing microorganism solution, the graphene oxide solution, and consolidating fluidsis (55-65):(2-8):(220-260); and (2) improving soil consolidation strength, comprising mixing urease microorganism solution, graphene oxide solution and consolidating fluids and carrying out soil consolidation reaction.
