The orientation-independent SSPC analysis also indicated that the internal friction and cohesion of rock mass, as well as the slope height and dip angle
, are the important parameters in the stability of slopes.
This study focused on the effects of both permanent fault displacements and dynamic ground motions on tunnel lining's response, including internal load distribution, displacement, and shear distortion of the lining section under reverse fault rupture at dip angle
of 45[degrees] and in an earthquake magnitude of 7 (i.e., the imposed fault displacements correspond to earthquake with Ms 7) (see Table 3).
Gutscher et al., (1999) interpret the seismic gap at intermediate depths to the north of Ecuador between 0[degrees]N and 1[degrees]S to the subduction of the Carnegie Ridge and the changes in the dip angle
in the Transition zones as tearing of the Nazca plate.
In addition, the Q-S curves for intact bedrock are shown as in Figure 12(a) and the Q-S curves for jointed bedrock with the dip angle
of 45[degrees] are shown as in Figure 12(b).
The lining shear distortion for FW1D case did not increase by increasing fault displacement, except for fault dip angle
75 [degrees] (i.e.
The first group is likely associated with the plate interface and follows an apparent 20[degrees] dip angle
from the trench towards the coastline.
In Case 1, the rupture was initiated at the low dip angle
part of BCF3, and then it propagated to deep area BCF4 and to shallow area BCF2 and PGF.
Furthermore, as the dip angle
only differed with a maximum variation of 0.04[degrees], it was indeed a test to the performance of the sensor.
The laboratory results show that the fracture curve forms an approximate U-shaped distribution with the dip angle
being changed, and the rockmass strength reaches its minimum value when the dip angle
where [[sigma].sub.n] and [[tau].sub.n] are the normal and shear stresses of the fault plane, respectively, MPa; [[sigma].sub.1] and [[sigma].sub.3] are the maximum and minimum principal stresses, MPa; [alpha] is the fault dip angle
measured in degrees ([degrees]).
where [[sigma].sub.n] is the general stress of the fault zone; [[tau].sub.n] is the shear stress of the fault zone, MPa; and [theta] is the dip angle
When a bedrock fault is covered with a certain depth of soil, the dip angle
, the displacement of the fault, and the soil parameters can be determined.
