Experiments are made on frozen sand and frozen clay respectively at the temperature of - 7℃, - 12℃and - 17℃. Of the data obtained, regression analysis and gray-system correlation are conducted. As indicated by the results, the frozen soil tensile strength is closely correIated with the P wave velocity and the compressive with the S wave, hence the former is well described by the latter.展开更多
