Time-Lapse Electrical Resistivity Investigations for Imaging the Grouting Injection in Shallow Subsurface Cavities
Figure 6
The postgrouting electrical resistivity results at test site: (a) inverted 2D electrical resistivity of line 6 when the grouting material overflows from subsurface cavities; (b) the results show movement of grout material toward line 6; (c) postgrouting 3D electrical resistivity distribution at the test site; the 3D resistivity distribution suggest that grout material moved toward the north side of the study area.
