Polymer Cut-off wall is a new kind of anti-seepage work used in hydraulic and civil engineering. It is quite different from concrete cut-off wall in materials and sizes. Traditional quality testing methods such as elastic wave tomography, GPR and resistivity imaging are all not applicable in polymer cut-off wall quality testing. We design a new testing method based on DC potential measuring. We use electrodes to build underground electric field and measuring the change of potential near the wall to analysis the integrity of the wall. We finish a series of indoor model and some full-scale tests. The results prove that the method is effective and practicable in polymer cut-off wall quality testing. |
