With a stack body of some hydroelectric power station left bank as an example,in order to obtain rubble anti-hear intensity parameters, the results of the direct shear test and triaxial compression test were compared and analyzed. Experimental results show that: the rubble anti-hear intensity parameters measured by the triaxial compression test are more true and accurate and the applicable conditions of the two test results are also expounded; fast-hear test is fit for a high-peed plastic clay which has a smaller permeability coefficient and is to be loaded fast, but it is not fit for the soil which possesses anisotropy and unknown shear-reaking surface,in addition, in comparison with triaxial compression test,the results of fast-hear test are quite different for coarse-rained soil which possesses stronger permeability; the non-onsolidated and undrained shear test is suit for general clay and sand soil, except soil disturbed easily, and the test results are closer to the real.
