Abstract:
The geology in Ohio is characterized by the

presence of gently dipping, harder, more competent

strata (siltstones, sandstones, limestones) alternating

with softer, less competent strata (claystones,

mudstones, sha les). This type of stratigraphy is

highly susceptible to differential weathering which

results in undercutting of the competent layers by

erosion of the incompetent layers. Undercutting

promotes a variety of slope movements such as

rockfalls, plane failures, and wedge failures that

may not occur otherwise. Many of the slope failures

in Ohio initiate as plane failures and wedge failures

in competent strata at higher elevations and descend

as rockfalls. The frequency and size of these falls

depend upon joint spacing within the competent

unit and the extent by which it has been undercut.

The undercutting- induced failures can be quite

hazardous because of their instantaneous

occurrence, high speed, and occasionally large

volume of rock involved. There are many road cuts

in Ohio, however, where closely jointed rock units

lead to rockfalls without the presence of

undercutting. This study was undertaken to develop

a rating matrix that could be used to rank order the

slopes in terms of their hazard potential with respect

to rockfalls.
