slope failure

[′slōp ‚fāl·yər]
(geology)
The downward and outward movement of a mass of soil beneath a natural slope or other inclined surface; four types of slope failure are rockfall, rock flow, plane shear, and rotational shear.

The results also showed that medium spatial resolution imagery (ASTER) may well be utilized in an irregular topographic area like the Himalayas to inevitably distinguish above 90% of slope failures.
The fuzzy set theory has been used in the past to analyze the potential of a slope failure. These studies successfully demonstrated how the fuzzy neural network could assist preparing for a potential slope failure; however, the fuzzy neural networks have not been used for predicting slope failure [14-18].
Consequently, the 2016 Yanchao mudstone landslide provides a unique opportunity to examine the driving mechanism and dynamic process of these slope failures.
A., Threshold values of shear strength parameters of soils taken from slope failures and stable slopes in Malaysia.
Some were selected for their well-known changes, as in the case of the sand dunes at Shallow Bay and the mouth of Western Brook, and the frequent slope failures along Western Brook Pond, Lookout Hills, and the inner Trout River Pond.
Slope Failure Analysis Results: The shear strength parameters (c and ph) obtained from direct shear tests performed at in situ field density for varying degrees of saturation (Table-2), were utilized in Slope/W software for the slope failure analysis.
The infiltration process wetted the soil layer at shallow depth near the slope surface and may lead to slope failure during a prolonged rainfall event.
The county could be held liable if pedestrians were injured in or around a slope failure.
These procedures also outlined quantitative evaluation on the effectiveness of root systems planted to prevent shallow, infiltration-induced movements of unsaturated slopes in tropical areas, where many slope failures are caused by infiltration-induced pore pressure changes rather than by a rise in the ground watertable.
Additionally, it was shown that the use of horizontal drainage results in the decrease of the pore water pressure inside the slope and avoids surface erosion and progressive slope failure.
The Banihal- Qazikund tunnel, on the other hand, will provide relief from roadblocks due to slope failure, rock fall, and avalanche.
