If they're a pair and are adults, and she's trying to dig, its likely she's gravid. Its important she's given an appropriate nest box so she can lay the eggs, and binding doesn't occur. If she actually is gravid, double up on the calcium for a while to replace what was lost in the egg creation. Other things can cause what you're describing too, stress for one. Male beardies tend to be a little pushy, and will almost always try to take the best basking spots, the best food, etc. The female may be simply trying to get away from him the only way she knows how.
Anyway, all the beardies I've dealt with are kind of picky about how they want a nestbox to be made. I generally end up moving them to a large Rubbermaid type tub nearly filled with a mix of organic humus, peat, and play sand. I give her at least a good foot deep to dig in, and put a heat pad underneath it. Every time, they go right to the warmest, and deepest spot to lay.
She sits in her corner, singing herself to sleep.
Wrapped in all of the promises, that no one seems to keep.
