The strong decays of the $D_{s1}(2710)$ and $D_{sJ}(2860)$ are investigatedin the framework of the $^3P_0$ model. Its decay properties newly reported bythe BaBar Collaboration can be reasonably accounted for in the presence of the$D_{s1}(2710)$ being a mixture of the $D_s(2 ^3S_1)$ and $D_s(1 ^3D_1)$. Theorthogonal partner of the $D_{s1}(2710)$ is expected to have a mass of about$2.66\sim 2.9$ GeV in quark models and a width of about $40\sim 60$ MeV in the$^3P_0$ model. The predicted decay properties turn out to be consistent withthe BaBar's new data in both the orthogonal partner of the $D_{s1}(2710)$ andthe $D_s(1 ^3D_3)$ interpretations for the $D_{sJ}(2860)$. The availableexperimental information is not enough to distinguish these two possibilities.The $E1$ radiative transitions of the $D_{s1}(2710)$ and $D_{sJ}(2860)$ arealso studied. We tend to conclude that the $D_{s1}(2710)$ can be identified asa mixture of the $D_s(2 ^3S_1)$ and $D_s(1 ^3D_1)$, and the $D_{sJ}(2860)$could be either the orthogonal partner of the $D_{s1}(2710)$ or the $D_s(1^3D_3)$. Further experimental information on the $D_{sJ}(2860)$ in the$D_s\eta$, $D^\ast_s\eta$, and $DK^\ast$ channels is needed.
