Rig #1826, based in Big Spring, Texas, along with a bundled Basic high-spec ancillary equipment package successfully drilled out frac plugs over a total horizontal displacement
of 17,935 feet.
The excess pore water pressure ratio ([r.sub.u]) and the predicted horizontal displacement
corresponding to depth are analysed in this study.
The free horizontal oscillations of the system are measured by the horizontal displacement
sensor after turning off the magnetic fixture.
Deductions are made for poor form or horizontal displacement
from the center of the bed.
The horizontal displacement
of the foundation in relation to the base (shake table) is prevented, while the rocking and uplifting of the foundation is allowed.
Only settlements were found, and the horizontal displacement
was smaller than the vertical displacement in the existing tunnel.
Figures 4-5 show the variations of horizontal displacement
[u.sub.x] and vertical displacement [u.sub.z] along the horizontal direction at the ground surface with the homogenous WIB (where the gradient index [gamma] = 0) and the graded WIB (where the gradient index [gamma] = 5).
The horizontal modeled coseismic displacement pattern (Figure 7(a), black arrows) generally converges toward the largest displacement area, except for the region close to the surface trace of the two faults and ESE along the strike direction, where the horizontal displacement
is outgoing from the epicenter zone.
The fly ash has such a smaller density that the horizontal displacement
of the wall is smaller and the effect is obvious, compared with the silty clay as a filler.
Both Knothe and Litwiniszyn in their theories assumed (following Avershin) that between the U horizontal displacement
vector and the T tilt vector, there is proportionality:
This method works well for measuring horizontal displacement
and it face problems when measuring vertical displacement.
