It showed that these deep cracks in concentrated unloading zone generally dip towards the river or to the inner slope with high angle, and the cause of formation due to the category of unloading. The concentrated unloading is the product of the epigenetic deformation along the original tectonic structural planes accompanied by the stress release of slope during the formation process of river bank slope.
