Abstract Enzyme induced calcium carbonate precipitation(EICP) technology has good application prospect in reducing infiltration of silt soil in yellow river flooding areas. Here, the premixing method was used to treat the silt soil samples, and the permeability coefficient of the samples was measured by falling-head permeability test, and the microscopic characteristics of EICP seepage reduction were explored by scanning electron microscopy. The permeability coefficient, calcium carbonate production amount and pore changes of silt sand soil before and after treatment with different dry densities and EICP treatment times were obtained. From the research results, as the dry density increases, the permeability coefficient of the treated sample first decreases and then increases, and the amount of calcium carbonate produced first increases and then decreases. With the increase of EICP treatment times, the permeability coefficient gradually decreased, and the calcium carbonate production gradually increased. Whether to the permeability coefficient or to calcium carbonate production, the variation was the most significant after the first treatment. After 6 treatments, the permeability coefficient of silt sand soil can be reduced to a minimum of 1.64×10^-4 cm·s^-1, and the maximum calcium carbonate production amount can reach 5.82%. Through the microscopic analysis, the porosity and pore area of the treated samples both decreased, and the average porosity decreased by 7.28%, and the maximum reduction was occurred to the sample with a dry density of 1.55 g·cm^-3, it's porosity decreased by 8.87%, and it's pore area decreased by 8.64%, and it's macropore area decreased by 48.59%, which caused the change of macroscopic permeability coefficient.
