Figure 8. Graph of the stability coefficient Fs depending on the pore water Ru<br />
Based on the obtained results from<br />
these input parameters it could be concluded<br />
that the adopted geometrical elements,<br />
affected by the stability coefficient<br />
using the all methods of calculation, is<br />
greater than 1 for the pore water coefficient<br />
Ru < 0.2.<br />
Also, it has to be repeated that there<br />
are no known the exact values of the pore<br />
water coefficient. To obtain the accurate<br />
results, it is necessary to set the piezometer<br />
per analyzed profile in order to obtain<br />
the accurate data at the level of ground<br />
water in deposit, before the waste disposal.<br />
It is also necessary to constantly<br />
monitor any changes in the work environment<br />
(cracks, landslides, subsidence).<br />
CONCLUSION<br />
Software GeoStudio 2007 - SLOPE /<br />
W is a program that can accurately determine<br />
all relevant conditions for calculation<br />
of slope stability in open pits, waste<br />
dumps and earth dams.<br />
Each member of the lithological profile<br />
could be realistically modeled by spatial<br />
location and physical - mechanical<br />
characteristics.<br />
It is also possible, in many ways, to<br />
model the impact of groundwater on the<br />
stability as well as the surface loads on the<br />
substrate surface.<br />
Using this software significantly reduces<br />
the calculation time compared to the<br />
classic design.<br />
For design, with proper initial selection<br />
parameters, the designer is still the<br />
most important designer. However, by the<br />
use of computer software, the job of designer<br />
is much easier in terms of time and<br />
quality due to rapid analysis capabilities in<br />
order to select the best solution.<br />
