The unconfined compressive strength (UCS) of rock is a basic parameter for the design of foundations resting on rock. However, it is often very difficult to retrieve intact rock core specimens for the UCS test due to mechanical breaking or natural fracturing of the rock core during the drilling process. In such cases, it becomes …
