Abstract

Abstract

The effect of agent injection in-situ is the key to the results of site remediation. Therefore, evaluating the effect of agent injection is of great significance to site in-situ remediation. In this paper, the effect of agent injection in the process of in-situ repairing a coking site in Yunnan was evaluated by using the cross-hole earth resistance imaging method (ERT). The transmission and distribution of the repairing agent were estimated according to the underground electrical information and electrical changes before, during and after perfusion. The results showed that the changes in water temperature, pH, conductivity, redox potential, dissolved oxygen and other basic water quality parameters of the groundwater in the monitoring wells before and after the injection, were basically consistent with the electrical changes of the 2D and 3D profiles of the site, indicating that the injection effect of the repair agent was good, and it was confirmed that ERT had good feasibility and applicability in the evaluation of injection effect of the in-situ repairing agents, which can provide a reference for the in-situ repairing of similar sites.
