| Abstract: | In this paper, the rock freeze-thaw test in China Hydropower Industry Standard Code for rock tests of hydroelectric and water conservancy engineering (DL/T5368-2007) and American ASTM Standard are compared. The results show that there are differences in specimen size, freeze-thaw temperature, freeze-thaw time and freeze-thaw circulation between the two standards, and the possible effects of these differences on the test results are further analyzed. This paper puts forward the problems that should be paid attention to by Chinese hydropower engineers when using American ASTM standard to carry out the test. Through this study, it can provide valuable reference and solutions for our hydropower engineers to undertake international projects. |
