The technical scheme of the method is as follows: firstly, preparing urease-producing microorganisms and cementing liquid raw materials into high-concentration suspension; then mixing the high molecular resin with the water absorption rate of 400-800 times with the high molecular resin; then mixing a proper amount of the mixture with soft soil, and quickly reducing the water content of the soft soil to the optimal water content of + 6-8%; the mixture forms MICP reaction particles, calcium carbonate is separated out through reaction, liquid water is consumed, the water content of soft soil is further reduced, and the filling effect of the calcium carbonate can remarkably improve the soil strength. And then, uniformly mixing 4-7% of lime and a soil body, paving the mixture as a roadbed material, gradually hardening the soil body after rolling and forming, and meeting the requirements of compactness, strength and water stability of roadbed filling due to the solidification effect of the lime. The method can not only make full use of the excavated waste soil in the engineering and protect the environment, but also has fast construction speed and simple and easy operation.)
