GROUTING MONITORING METHOD USED RESISTIVITY
Disclosed is a rock grouting monitoring method using resistivity. A rock grouting monitoring device comprises: a plurality of bore holes radially installed on an underground structure to form a grouting unit by injecting grout into rock or the ground around the underground structure; a plurality of electrodes installed in the bore holes; and a plurality of temperature sensors installed in the bore holes to measure a temperature of the rock or the ground. The rock grouting monitoring method comprises: (a) a step where a measurement unit applies a current or a voltage to the electrodes, and the temperature sensors measure the temperature of the rock or the ground; (b) a step where the measurement unit measures a resistance value between the electrodes installed in bore holes adjacent to each other; and (c) a step where a grouting analysis unit analyzes measurement values of the temperature sensors and the measurement unit to calculate resistivity.
전기비저항을 이용한 암반그라우팅 모니터링 방법이 개시된다. 개시된 암반그라우팅 모니터링 방법은 지하구조물 주변 암반 또는 지반에 주입재(grout)를 주입하여 그라우팅부를 형성하기 위해 지하구조물에 방사형으로 설치된 복수 개의 보어홀(bore hole)과, 보어홀 내부에 설치된 복수 개의 전극과, 보어홀 내부에 설치되어, 암반 또는 지반의 온도를 측정하는 복수 개의 온도센서를 포함하는 암반 그라우팅 모니터링장치에 있어서, (a) 측정부가 전극에 전류 또는 전압을 인가하고, 온도센서가 암반 또는 지반의 온도를 측정하는 단계; (b) 측정부가 상호 인접한 보어홀에 설치된 전극간 저항값을 측정하는 단계; (c) 그라우팅 분석부가 온도센서 및 측정부의 측정값을 상호 분석하여 전기비저항값을 산출하는 단계;를 포함한다.
