CORRELATION STUDY ON ENGINEERING PROPERTY INDEXES OF THE TERTIARY SANDSTONE IN ONE NUCLEAR POWER PLANT

A large number of experimental data indicators that there is a good correlation between the physico-mechanical property indexes of rock and soil. On-site and laboratory tests in a nuclear power plant are performed to investigate the space distribution and correlation of dynamic parameters and static parameters. Also carry out some statistics and analysis on the engineering property indexes of the tertiary sandstone. Regression analysis indicates that there exists good correlation between natural uniaxial compressive strength and natural density, elastic modulus, pressure meter test parameters and shear wave velocity. Correlation equations are established to make it useful on geotechnical engineering designing and construction.
