Abstract
Disclosed is a method of evaluating a ground reinforcement effect using 4-D electrical resistivity monitoring, wherein the ground reinforcement is made up on an underground cavity through cement mortar grouting, the method including: (a) installing a survey line for measuring electrical resistivity in a ground reinforcement zone; (b) measuring the electrical resistivity of the ground reinforcement zone through the survey line before grouting mortar, and imaging three-dimensional electrical resistivity distribution in the ground reinforcement zone by applying a three-dimensional electrical resistivity inversion to the measured results; (c) measuring the electrical resistivity of the ground reinforcement zone through the survey line while or after grouting the mortar, and imaging the three-dimensional electrical resistivity distribution in the ground reinforcement zone by applying the three-dimensional electrical resistivity inversion to the measured results; and (d) calculating a change ratio of the electrical resistivity measured while or after the grouting in (c) to the electrical resistivity measured before the grouting in (b), and evaluating the ground reinforcement effect by imaging the three-dimensional electrical resistivity distribution in the ground reinforcement zone on the basis of the change ratio.
