In order to improve the shear properties of basalt residual laterite，four kinds of curing agents，such as cement，lime，sodium silicate and cement-sodium silicate double slurry，were mixed into basalt laterite respectively.The immersion shear test was carried out，and the internal mechanism and influence of different curing agents on the improvement of the shear strength of basalt laterite were studied. The results show that the addition of curing agent can improve the cohesion and internal friction angle of laterite after soaking water，and significantly improve the shear strength of laterite. When 10% cement is added，the shear strength of the modified basalt laterite can reach 161.42 kPa，and the strengthening effect is the best. When 10% cement and sodium silicate double slurry are added，the shear strength is 112.07 kPa；When adding 10% lime or 10% sodium silicate，the enhancement effect is relatively poor.
