There's an important trick that no-one above has mentioned.
When you fill a bath with water, the weight of the water is very heavy - much heavier than a person in the bath. Unless its a cast iron bath, the whole bath will move down slightly. This puts tension on the silicon filler material and stretches it. Invariably it breaks. We are only talking about one millimetre here.
The trick is to fill the bath with water just before you start and keep it in there for at least 24 hours. When you empty the bath it rises a bit but this time compresses the silicon filler.

If your silicone caulking is cracking it can be from no other reason than movement between the two surfaces being caulked. You will need to stop the movement as Carrust said . It may seem like a lot of effort,but if you do it your seal should last for years just as mine have. If the tub apron is properly supported filling the tub or leaving it empty will make no difference. As others have told you, a clean ,dry surface is always needed, but it won't help if there is still movement.
