摘要：

This paper presents an evaluation of change in microstructure of Hefei expansive soil using electrical resistivity measurements. The swelling tests were performed on the in-situ sampled xpansive soils with a modified oedometer consolidation cell. The vertical and horizontal electrical resistivities were measured during soil swelling. The electrical parameters, such as the average formation factor, the electrical anisotropy index and the average shape factor were calculated and evaluated. Experimental results showed the electrical resistivity method can be used to quantitatively evaluate the change in microstructure of Hefei expansive soils during swelling.
