摘要：

A general equation, derived from three published equations, is proposed for the correction of uniaxial compressive strength test results to a length-to-diameter ratio of two. In addition, an equation is given for standardization of test results to a length-to-diameter ratio of two and 50 mm diameter. The methods have been tested by analysis of over thirty sets of test data from the literature. Results for correction to length-to-diameter ratio of two fall within a 10% error band of the experimental value equivalent to a length-to-diameter ratio of two. The two-stage correction to a length-to-diameter ratio of two and 50 mm diameter, from a range of specimen lengths and diameters, gives results which are lower than the direct test values for specimens with these dimensions.
