초록
To investigate the engineering properties of basalt in Cheju Island, rock samples of Pyosenri basalt, trachy-basalt and scoria were taken from Seoguipo-Si Seongsan-Eup area. The laboratory tests such as absorption test, specific gravity test, permeability test, Schmidt hammer test, elastic wave test and uniaxial compressive testwere carried out for the collected rock samples. The absorption, the specific gravity, the permeability, the elastic wave velocity and uniaxial compressive strengthwere investigated and analyzed as the results of these tests. As the result of regression analysis for the relationship between the rebound values from Schmidt hammer test and the uniaxial compressive strengths from uniaxial compressive test, especially, estimation equations were proposed using the rebound values from Schmidt hammer test. Therefore, the simple method to estimate the uniaxial compressive strength was provided.
