| Abstract: | In this paper,the applicability of determining the expansive index-rate of expansion load-free expansion ratio and expansive pressure of swelling rock with the testing standard for expansive soil are studied.The procedures unsuited to swelling rock,are modified to ensure the accuracy of testing results.Therefore,the testing method of swelling rock is expected to be more precise. |

| Keywords: | Swelling rock Rate of free expansion Rate of expansion Expansive pressure |
