PURPOSE: A method for reinforcing soil by using biopolymer is provided to reinforce the strength of soil effectively, to be environment-friendly by using biopolymer which is polysaccharide generated from organism. CONSTITUTION: A method for reinforcing soil by using biopolymer comprises: a step of reinforcing strength of whole soil by adhesion increase between soil particles and biopolymer polymer chains by mixing biopolymers and soil. The biopolymer is one or more selected from a group consisting of beta glucan, xanthan gum, chitosan, gellan gum, and curdlan. The soil is residual granite soil. The beta glucan is mixed with soil within the moisture content range of 60%.
