초록

암반에서 공사를 수행하는 경우에는 공사의 안정성 확보를 위하여 대상 암반의 일축압축강도를 정확히평가해야 한다. 그러나 일축압축강도를 산정하기 위해서는 많은 비용과 시간이 필요하다. 또한 현장에서는 암석의 일축압축강도시험을 수행할 수 없다는 문제점이 있다. 이러한 문제를 해결하기 위해 점하중강도 시험을 이용하여 암석의 일축압축강도를 산정하는 방법이 외국의 많은 연구자들에 의하여 조사되었다. 그러나 외국의 암석에서 얻어진 연구결과를 그대로 국내에서 적용하는 것은 신뢰성에 문제가 있을수 있다. 본 연구에서는 국내 암석에 대한 점하중강도지수와 일축압축강도의 상관관계를 광범위한 국내외 문헌조사와 실내시험 결과를 통하여 도표로 제시하였다. 본 연구결과는 국내 암석의 일축압축강도를간편하고 신속하게 추정하는데 활용될 수 있을 것으로 기대된다.

Abstract

Accurate estimation of the uniaxial compressive strength of rock is very crucial for the safety of construction activities occurring in the rock mass. However, the uniaxial compressive strength test is expensive and time consuming. Moreover, the uniaxial compressive strength test cannot be performed in the field. In order to solve this kind of problem, many foreign researchers investigated the use of the point load strength test for the estimation of uniaxial compressive strength of rock. However, the result of research obtained for rocks from other countries may not be directly applicable for rocks in Korea. The correlation between the point load strength index and the uniaxial compressive strength for rocks in Korea is suggested in the form of table by using the results of the extensive literature reviews and laboratory tests. The suggested result is expected to be used for the simple and quick estimation of uniaxial compressive strength of rocks in Korea.
