Description

상대함수율에 따른 전기비저항 측정 장치{Soil Cylinder for Measuring Soil Resistivity According to Relative Water Content}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electrical resistivity measuring device,

본 발명은 전기비저항 측정에 관한 것으로, 구체적으로 배기구를 갖는 원통형의 측정 대상물 수용 실린더 및 측정 대상물에 응력을 가하기 위한 가압판을 구비하여 상대함수율과 전기비저항을 동시에 측정할 수 있도록 한 상대함수율에 따른 전기비저항 측정 장치에 관한 것이다.More specifically, the present invention relates to a cylindrical measuring object accommodating cylinder having an exhaust port and a pressure plate for applying stress to the measuring object, and is capable of measuring relative humidity and electrical resistivity simultaneously, And a resistivity measuring apparatus.

직접 탐사가 불가능한 지하 암반이나 토양 등의 지구물리학적 특성을 규명하기 위하여 이용되는 물리 탐사 방법 중에서 전기비저항 탐사는 지하 매질의 전기비저항 차이에 의해 야기되는 이상 전위차를 측정하여 지층의 구조, 암석의 분포상태 등 지하구조, 조암광물, 공극률, 공극수의 전기전도도, 공극의 포화도 등을 규명하는데 매우 유용하게 이용되는 물리 탐사기술이다.Among the geophysical methods used to investigate the geophysical characteristics of underground rocks and soils, which can not be directly surveyed, electrical resistivity survey was conducted by measuring the abnormal potential difference caused by the difference in electrical resistivity of the underground medium, It is a geophysical exploration technique that is very useful for identifying underground structures, rocky minerals, porosity, electrical conductivity of pore water, and saturation of pores.

지하 암반 등의 물성 파악을 위해 실험실에서 이루어지는 전기비저항의 계측은 통상 현지에서 채취한 암석 등의 시편 양측에 전류 전극을 통하여 전류를 흘려보낸 뒤 그 두 전극 사이의 전위차를 측정하여 전기비저항을 계측하는 방식으로 이루어진다.In order to measure the electrical resistivity in the laboratory for the purpose of understanding the properties of underground rock, etc., electric current is flown to both sides of the specimen such as rocks collected in the field, and the electric potential difference between the two electrodes is measured to measure the electrical resistivity .

이러한 전기비저항 계측에 있어서 암석의 전기비저항을 좌우하는 가장 큰 요인은 공극률과 함수율이다. 따라서 암석 시편의 전기비저항을 정확하게 측정하기 위해서는 측정이 이루어지는 동안 암석 시편과 전극을 충분히 압착하면서 시편이 마르지 않게 유지하는 것이 매우 중요하다.In the electrical resistivity measurement, the porosity and water content are the main factors that influence the electrical resistivity of the rock. Therefore, in order to accurately measure the electrical resistivity of rock specimens, it is very important to keep the specimens dry while compressing the rock specimens and electrodes thoroughly during the measurement.

한편, 토양의 전기 비저항은 토양의 물리적 성질인 공극율, 간극수의 전기 비저항, 포화도, 투수 계수 등과 밀접한 관련이 있어 토양의 물리적 특성을 공간적으로 분석하는데 유용한 자료로 사용될 수 있다.On the other hand, electrical resistivity of soils is closely related to porosity, electrical resistivity, saturation degree and permeability coefficient of pore water, and can be used as a useful data for spatial analysis of soil physical properties.

그러나 토양층에서 깊이별로 토양의 물리적 성질을 밝히는 일은 주로 시추를 통해 얻은 심도별 시료를 실험실 조건에서 분석하여 결과를 얻는 것이 일반적이었다.However, it is common to find out the physical properties of soil by depth in soil layer by analyzing in depth samples obtained from drilling in laboratory conditions.

그러나 시추를 이용하는 경우는 비용이 많이 발생할 뿐만 아니라, 시추에 따른 오염 등의 재해에 취약한 단점이 있다.However, when drilling is used, it is not only costly but also is vulnerable to disasters such as pollution caused by drilling.

또한, 시추에 의해 결과를 얻을 경우, 1차원 데이터만을 얻을 수 있으므로 공간적인 토양의 물리적 특성을 구현하는데 한계가 있었다.In addition, when the results are obtained by drilling, only the one-dimensional data can be obtained, so that there is a limit to realizing the physical characteristics of the spatial soil.

특히, 종래 기술의 시편 전기비저항 계측 방법들에 따르면 실제와 유사한 조건에서의 측정이 불가능하여 계측한 시편의 전기비저항을 토대로 지하 암반이나 토양의 물성을 규명하는 경우 계측의 정확성과 신뢰도가 떨어지는 문제점이 있었다.Particularly, according to the conventional method of measuring electrical resistivity of specimen, it is impossible to measure under the condition similar to the actual condition, and the accuracy and reliability of the measurement are inferior when the physical properties of the underground rock or soil are identified based on the electrical resistivity of the measured specimen there was.

즉, 현장에서 채취한 흙의 경우 압력해방으로 인하여 현장조건하에서의 전기비저항 측정이 불가능하다. 종래 기술의 전기비저항을 측정하기 위한 소일 실린더의 경우에도 압력을 가하는 장치가 없어 실험실에서 측정할 경우 현장의 응력 조건을 재현할 수 없다.That is, in the case of soil collected on site, it is impossible to measure electrical resistivity under field conditions due to pressure relief. Even in the case of the soilless cylinder for measuring the electrical resistivity of the prior art, there is no pressure applying device, so that the stress condition in the field can not be reproduced in the laboratory.

또한, 실린더 주위에 배기구가 없어 상대함수율에 따른 흙의 전기비저항 측정이 불가능하다.In addition, there is no exhaust hole around the cylinder, and it is impossible to measure the electrical resistivity of the soil according to the relative water content.

특히, 종래 기술에서 시편의 상대함수율과 전기비저항을 측정하기 위해서는 다음과 같은 방법이 이용된다.Particularly, in the prior art, the following method is used to measure the relative water content and electrical resistivity of a specimen.

종래 기술에서는 동일한 항온항습 환경 하에서 시간 경과에 따른 시편의 상대함수율과 전기비저항을 각각 계측 → 동일 건조 시각에 따른 상대함수율과 전기비저항을 비교 → 상대함수율에 따른 시편의 전기비저항을 산출의 과정을 수행하여,In the prior art, the relative water content and electrical resistivity of the sample are measured with time under the same constant temperature and humidity environment, and the relative water content and electrical resistivity are compared with each other at the same drying time. The electrical resistivity of the sample is calculated according to the relative water content So,

상대함수율과 전기비저항을 동시에 계측할 때와 비슷한 결과를 추정하는 것으로 상대함수율과 전기비저항을 동시에 측정하는 것이 불가능하다.It is impossible to simultaneously measure the relative water content and electrical resistivity by estimating the results similar to those obtained when simultaneous measurement of relative water content and electrical resistivity.
