side in-plane strong of a little depth soil mass. In contrast to the effect
of vertically-enlarge roots, whereby soil is strengthened by an increase
in its shear strength, the pulling effect strengthens the soil by increasing
the tensile strength of the rooted soil zone. To verify whether or not
a pulling effect exists in the root system of Prunus avium in the
Roudsar, North Iran and to study the importance and size of this effect,
a direct in situ test was led at a site in the Chaboksar Forests.
The results from the site showed that, in the surface soil (0-30 cm),
Side roots can provide a pull force of up to 490-712 N (Newtons) over
a vertical cross-section area of 20-50 cm2, or an enhance in
the pulling stability of the rooted soil by about 48.1%. The test results
suggest that, together with the Prunus avium vertical roots, which
keep the little depth rooted soil zone to the deep and more stable soil
mass, the side roots of the Prunus avium, with their pulling effect,
are able to make less against little depth instability in the forest slopes,
such as little depth slide, to a certain degree.]]>Abernethy, B. and I.D. Rutherfurd,200025921937Abernethy, B. and I.D. Rutherfurd,2001156379Bibalani, G.H., B. Majnonian, E. Adli and H.
