A dip angle
smaller than 90[degrees] is likely to induce sliding failures, while a value lager than 90[degrees] is likely to induce toppling failures.

faults of the damage height of superincumbent stratum.
In the orientation-independent stability analysis, the [H.sub.max] of SN-2 for stability was calculated to be 8.22 m for a dip angle
In the developed numerical model, a thrust fault propagated at the dip angle
of 60[degrees] with a vertical displacement of [DELTA]H/H=0.08 ([DELTA]H is the vertical displacement, and H is the depth of soil) and a circular tunnel located at FW1D (FW denotes footwall, D is the tunnel diameter and 1D denotes the horizontal distance between the lining center and the fault tip line in bedrock).

Two transition zones are observed which suggest a steep change in dip angle
. The first zone at 4[degrees]N is within the Cali A segment and the second zone at 2[degrees]S is within the Quito D segment.
In the early stage of loading, the joints of the rock experienced the process of closure regardless of the size of the dip angle
For HW1D case, by increasing fault dip angle
from 45[degrees] to 75[degrees], the horizontal and vertical displacements at the tunnel vault and the invert, decreased and increased, respectively.
In general, it is accepted that in the Southern region, the Nazca plate continuously subducts with a 30[degrees] dip angle
down to about 300 km depth; while in the Central region, the plate subducts with an initial 10[degrees] dip angle
from the trench to the coastline, increasing to a 30[degrees] dip to a depth of 120 km, and then becoming almost horizontal up to distances of 500 km from the trench.
Study on seismogenic structure of the Wenchuan earthquake showed that from south to north, the dip angles
of the Beichuan fault changed significantly, the dip increased from deep to shallow in the southwestern BCF, and the northeastern section of BCF had a greater dip angle
than the southwestern [1, 6, 24-27].
Concerning the dip angle
values, all of the three sensor nodes show an undulation.
. A numerical model (Figure 1) was created and then the different confining pressures, such as 1.5, 2.5, 3.5, and 6.0 MPa, were selected for performing numerical analysis according to the laboratory test values.
Drill holes crossing subvertical ore lodes at dip angle
Then, mechanical properties and progressive failure processes for rock masses with different dip angle
structure planes are studied, and the macroscopic fracture, mechanical responses, and AE responses of rock masses are analyzed.
The intersection of the fault and the roof plane is the origin O, while the angle with the Y-axis is the dip angle
[theta] of the fault (Asghar et al., 2018).
