암석의 역학지수 추정을 위한 간접시험법의 거동특성

Behavioral Characteristics of Rocks on Indirect Tests

  • 발행 : 2009.10.30

초록

본 연구는 국내에서 출토되는 화성암, 변성암, 퇴적암 1,417개 블록의 일축압축강도를 간접방법으로 도출하는 과정에서 각 시험법에 따른 강도발현의 거동 특성을 분석하였다. 퇴적암은 간접시험법에 따라 암석군에 상관없이 동일거동을 보이며, 압열인장강도를 매개로 시행한 과정에서는 암석군끼리 동일 거동 특성을 나타내고 있다. 이는 간접시험법을 적용했을 때에는 지질학적 생성원인에 따라 상관성해석을 시행해야 신뢰성 높은 결과를 도출할 수 있음을 암시한다.

To analyze the behavioral characteristics of rocks on indirect tests and uniaxial compressive strength, researchers have investigated 1417 pieces of rock block, which include igneous, metamorphic and sedimentary rocks in Korea. The same behavioral characteristics have been shown in every type of sedimentary rock and in the same species of rock in the case of Brazilian strength application. This suggests that correlations of rocks for geological considerations can lead to high reliability of the experimental results in case of an indirect method.
