One set is approximately horizontal with evenly spaced bedding planes with a dip angle varying slightly with the survey sites (basically maintained within 0[degrees]~5[degrees]) and the interlayer spacing is approximately 1.0 m, whereas the other set points to the foot of the north slope and inwards to the south slope with the dip angle and interlayer spacing varying significantly.
Step I: A model frame system is built, and two steel strips with 2 mm thickness, 50 mm width, and 1800 mm length are installed to assure the dip angle of faults (Fig.

The pole of intersection point of the joints lies within the friction cone or safe region because the dip angle of [J.sub.1] is very small.
When the dip angle of macrospores is low, the cohesion depends on the sliding friction of the fine-grained soil.
The calculation section pile cross is 1.5 m x 2.5 m, distance between piles is 4 m, rock-socketed depth is 6 m, the height of gravity retaining wall is 9 m, and dip angle of antisliding raking pile is 110[degrees].
In fact, both the fixed boundary conditions at the bottom and rolling conditions at the side of the hanging wall were changed to moving boundary conditions composed of horizontal and vertical displacement with the assumed fault dip angle, see Figure 1.
The effect of the parameters such as the slope dip angle on the CBH is discussed here.
Several studies have shown that this subduction zone may exhibit lateral variations in the dip angle of the subducted oceanic lithospere as well as changes in the distribution of seismicity along and down dip the trench, specially at intermediate depths (between the latitudes 3[degrees]N-4[degrees]N), where a seismic gap is apparent (Pennington, 1981; Taboada et al., 1998; Monsalve, 1998; Gutscher et al., 1999, Vargas et al., 2003, Mejia and Meyer, 2004, Chicangana and Vargas, 2004).
where [alpha] is the dip direction, [beta] is the dip angle, [DELTA][alpha] is the cell size on dip direction, [DELTA][beta] is the cell size on dip angle (Figure 2), [P.sub.A] is the corrected frequency in cell, [p.sub.AB] ([alpha], [beta]) is the joint probability density that the dip direction and dip angle are intersected by scanline, and P is the observed frequency in cell.
[7] carried out uniaxial compression test of shale rock and found that there are three kinds of failure modes for the jointed rock and that a change in the dip angle caused changes in the failure modes.
The configuration of the tunnel, fault rupture, boundary conditions, and fault dip angle adopted for numerical study are shown in Figure 2.
