Chemical grouting is used as an auxiliary method when underground structures are constructed in large cities. However, it is difficult to evaluate the qualities of solidified area by chemical grouting. To solve this problem, we note that electrical resistivity of chemical grout is much lower than the resistivities of ground and groundwater and investigate the possibility of evaluation of void filling by electrical resistivity. In this study, a series of electrical resistivity tests were performed on some saturated sands and some grouted sands in the laboratory. And the electrical-resistivity models of saturated sand and grouted sand, and the evaluation of chemical grout void filling by electrical resistivity are proposed.
