Objective To discuss the dispersion and correlation of granite in Foshan, analyze the causes of the dispersion and the measures to reduce the dispersion. Methods 10 groups of granite samples from a place in Foshan were selected for laboratory tests of physical and mechanical properties, and the data were analyzed statistically. Results The water content, bulk density, particle density and uniaxial compressive strength of granites in this area have a certain correlation, and there are discretization. Conclusion Analysis of the correlation and discreteness of test results is helpful to improve the reference value of test data and provide theoretical support for engineering applications.
