  We study circular Airy vortex beams (CAVBs) with a pair of point vortices
symmetrically loaded on the $x$-axis of initial plane. The two case of the
vortices with same and opposite signs are all studied. We only study the
relationship between properties of the focal pattern and the loading position
parameter (denoted as $d_v$) of the two vortices(so we set the absolute value
of topological charges being one.) Good agreements between simulation and
experiments have been achieved. We reasonably explains the behaviour of the
focal pattern as $d_v$ increases from small to large enough. The tailoring
effect of $d_v$ of the two vortices on the focal pattern may have potential
applications in optical micromanipulation, communications and other fields.
