Morphology

The meaning 'to collapse or fail suddenly because it is weak' is directly conveyed by combining 'fall apart' (to break/collapse) with the simile 'like a house of cards' (a fragile structure that easily collapses). All constituents are frequent and the simile is a common, cross-linguistic image, so a B1 learner who knows the words would readily infer the metaphorical meaning.

Etymology

Fall apart like a house of cards comes from the image of a house of cards made from playing cards: it looks tall but is very weak and will fall apart if you touch it. So the phrase means 'to collapse or fail suddenly' because weak plans or groups break just like that toy.
