OP, I think that the best thing that you can do is concentrate on your schoolwork. I live under similar circumstances; my parents aren't alcoholics, but almost the same. My relationship with my mother specifically has soured to the point that the second I go off to college, I might not come home ever again. I take refuge in my schoolwork; good grades equal good college opportunities equal escape from hell. I know it sounds crazy, but even that small shred of hope that I can find a way out of my family gives me the strength to move through to the next day. It might not be the ideal option, but it works. I've tried to fix our relationship, but at this point, it's too broken, and I think even my mom sees that. I've been looking into out of state colleges, possibly abroad, all so that I can escape.
If you have the opportunity, if he's not too far gone, you need to help him. Try to look online for tips about how to help an alcoholic, or if he goes too far, contact a helpline, and they'll help him rehabilitate. I wish you the best of luck!
