  We analyze $^{16}$O-$^{16}$O and $^{12}$C-$^{12}$C scattering with the
microscopic coupled-channels method and investigate the coupled-channels and
three-nucleon-force (3NF) effects on elastic and inelastic cross sections. In
the microscopic coupled-channels calculation, the Melbourne g-matrix
interaction modified according to the chiral 3NF effects is used. It is found
that the coupled-channels and 3NF effects additively change both the elastic
and inelastic cross sections. As a result, the coupled-channels calculation
including the 3NF effects significantly improves the agreement between the
theoretical results and the experimental data. The incident-energy dependence
of the coupled-channels and 3NF effects is also discussed.
