The CRRs of the iron and copper tailings in this study are similar to other kinds of tailings such as copper tailings and copper-zinc tailings. As mentioned above, the cyclic resistance of soil can also be studied with the CDSS test, and some of the reported data of CDSS tests are also illustrated in Fig. 7. The comparison between the CTX and CDSS tests indicates that the CRR values obtained from CTR tests
