Water saturation effect on the tensile strength of rocks
In underground cavern construction, rock is saturated to varying degrees due to the presence of ground water. This study aims to investigate the role of the degree of water saturation on the tensile strength of rocks.Three groups of specimens were tested. The first group of specimens was labelled “d...
