摘要：

In this paper, the microstructure of cement modified expansive soil was studied, and the variation of the structure parameters with the change of cement content was analyzed. The results show that the equivalent diameter of structure unit larger body content is more, the more the amount of cement, porosity, small structure unit is relatively reduced, reducing the fractal dimension of soil particles; The specimen structure element has a directional effect at located in 90 degrees. The changes of physical and mechanical properties of the samples are closely related to their microstructural characteristics.
