How old is she? How big is the laying bin? What type of material did you use (sand or dirt etc)? Is she acting normally right now, eating and drinking and basking? Were the eggs fully formed? Did she see you/another animal/get disturbed in any way while she was digging?
Sorry for all the questions just trying to get an idea of the issue. You can try putting her into a large bin, like a trash can or a deep storage box with a medium for her to lay in (most use play sand) around 12" deep and nothing else, and leave her in there all day and see if she starts digging again. If that doesn't work it might be time for a vet visit. Especially if she starts to show symptoms of egg binding, which would include sunken eyes, and lethargy, hanging around the bottom of the cage without laying more eggs, and a reluctancy to eat and drink. If it gets to this point it's very serious, at this point if she's not displaying symptoms yet give her a day or two in a big laying bin and take it from there.
