bcz liquid pressure increases with depth.
the pressure exerted by liquid is given by
pressure=density×height(depth)×gravity
this shows that pressure of a liquid increases as we go deeper and deeper.thus in dams water at bottom exerts more force per unit area as compared to water at surface.
therefore
the walls of dam are thicker near bottom so as to sustain the greater force exerted by water at bottom.
hope it helps u.if any query plz let me know.l will be grateful to clarify ur doubts.

HEY MATE ✌✌
HERE IS UR ANSWER ...
A dam is thicker at the bottom than at the top because the forces exerted are strongest close to the ground. Water pressure increases proportionally with depth, so the lower portion of the dam has greater water pressure exerted upon it. The increasing thickness of the lower dam also helps it support its own weight.
