  Measurements of two-particle correlations of inclusive and identified charged
particles performed with the ALICE detector in Pb--Pb collisions at
$\sqrt{s_{NN}} = 2.76 TeV$ are presented. The near-side jet shape is analyzed
in the low $p_{\rm T}$ regions ($1<$p_{\rm T}$<8GeV/c$). While the RMS of the
peak in $\Delta\varphi$-direction is independent of centrality within
uncertainties, we find significant broadening in $\Delta\eta$-direction from
peripheral to central collisions. The near-side $p/\pi$ ratio of particles
associated to a trigger particle from jet fragmentation in the central Pb--Pb
collisions is consistent with vacuum fragmentation in the measured momentum
region ($1.5<$p_{\rm T}$<4.5GeV\c$).
