  In the framework of the SU(3) chiral quark model, the $S-$wave baryon-baryon
bound states are investigated. It is found that according to the symmetry
character of the system and the contributions from chiral fields, there are
three types of bound states. The states of the first type, such as
$[\Omega\Omega]_{(0,0)}$ and $[\Xi^{*}\Omega]_{(0,1/2)}$ are deeply bound
dibaryon with narrow widths. The second type states, $[\Sigma^{*}
\Delta]_{(0,5/2)}$,$[\Sigma^{*} \Delta]_{(3,1/2)}$, $[\Delta\Delta]_{(0,3)}$
and $[\Delta\Delta]_{(3,0)}$ are also bound states, but with broad widths.
$[\Xi\Omega - \Xi^{*}\Omega]_{(1,1/2)}$, $[\Xi\Xi]_{(0,1)}$, and $[N
\Omega]_{(2,1/2)}$ are third type states. They, like {\em d}, are weakly bound
only if the chiral fields can provide attraction between baryons.
