Time-dependant stability of slopes excavated in marl

摘要

The soft rock weathering is considered on the basis of criteria used in various fields such as geology, engineering geology, mineralogy, soil and rock mechanics, and geomorphology. The problem of stability over time should be considered for slopes excavated in marl, in case they are not protected against weathering processes. In addition to disintegration of material on slope surface, the weathering also results in shear strength reduction in the interior of the slope. Principal processes leading to weathering are explained on the example of marl originating from flysch formations near Split.
