  Asteroseismology is a very useful tool for exploring the stellar interiors
and evolutionary status and for determining stellar fundamental parameters,
such as stellar mass, radius, surface gravity, and the stellar mean density. In
the present work, we use it to preliminarily analyze the 14 new-type pulsating
stars: Blue Large-Amplitude Pulsators (BLAPs) which is observed by OGLE
project, to roughly analyze their evolutionary status. We adopt the theory of
single star evolution and artificially set the mass loss rate of
$\dot{M}=-2\times10^{-4}~{\rm M_{\odot}/year}$ and mass loss beginning at the
radius of $R=40$ $\rm R_{\odot}$ on red giant branch to generate a series of
theoretical models. Based on these theoretical models and the corresponding
observations, we find that those BLAP stars are more likely to be the core
helium burning stars. Most of them are in the middle and late phase of the
helium burning.
