Hydraulic Force

Hydraulic pressures and forces are obtained on a typical slice, as used in current methods of slope stability analysis, under hydrostatic and flowing groundwater conditions. It is shown that current methods do not satisfy some basic hydraulics and soil mechanics principles. The effective normal stress on the lower boundary of a slice is shown to be underestimated, and the resultant hydraulic force is not accounted for adequately. Key words: effective stress, hydraulic pressure, hydraulic gradient, hydraulic force, slope stability.

Natural Slopes

Practical considerations for the use of subsurface exploratory data and material strength data in slope stability calculations for estimating the factor of safety along potential slip surfaces in natural slopes are described and illustrated with a sample problem. An alternative form of the slope stability equations for the method of slices, using the limit equilibrium method and satisfying complete statics on each slice, is presented for plane problems. The shortcomings inherent in commonly available computer programs for the analysis of slope stability problems are discussed. Means to overcome some of the limitations are indicated and illustrated with a sample problem. It is suggested that the general purpose computer programs for slope stability analysis should use the complete form of the slope stability equations. The alternative form of the equations and the discussion of their solution are valid for slope stability analysis of natural slopes and embankment dams. Keywords: stability analysis, slope stability, riverbanks, lake banks, natural slopes, soil mechanics, embankments.

The Stability

This study is about the stability conditions of a high cut slope as well as the possible measures of restoration, along the Egnatia Highway (deviation of Asprovalta). The study includes: the topographic map of the landslide and the 3-D view with the use of Geographical Information Systems, the analysis of geological and petrologie data from the samples of five core drillings, the soil mechanics laboratory tests, the determination of the causes and the landslide mechanisms and finally the slope stability analysis with «classic» methods such as Bishop, Janbu, Morgenstern-Price. A multiple repeated slope stability analysis took place in order to determinate the proper geometry (inclinations) of the slope with new benches. From the analysis of the data, the landslide restoration can be achieved with the combination of measures such as new benches geometry (proposed), surface drainage systems, retaining walls, soil nailing, geogrids and grass mat.
