Description 734-744
Slope stability of soil (Zhu et al.20
method used) has been studied under a random field. Spatial variability
of soil’s proprieties (random variables (RV) is decomposed in term of
deterministic trend and the random fluctuations of short duration of soil round
this deterministic trend. Spread of variation of these fluctuations from one
point to another in the soil is a very important parameter for describing the
natural variability of soil's proprieties. In this paper, to quantify tendency
value and dispersion of safety factors (FS) in function of trend and dispersion
of RV, one uses Point Estimated Method (PEM) validated by Monte Carlo Method
(MCM). It is known that the MCM has a prohibitive machine time compared to PEM,
where the advantage to use this last one. Unfortunately, the PEM don’t take
explicitly the fluctuations of RV into account. Therefore, one proposes to
incorporate it in the PEM.
