DC-Slope determines the safety from the slope and the base failure according to the approach:

• Krey-Bishop (friction circle) and
• Janbu (any sliding planes)

The ground surface and the layers may have any course. Ground water and seepage water levels may run arbitrarily and may be interpolated as curves. We may consider the artesian water pressure. The effects of the water levels (the weight under uplift or the weight of the water-saturated soil), the artesian pressure, the pore water pressure, and the pore excess pressure will be automatically considered.

Any constructions, components and anchors may influence the determination:

• Constructions (buildings) operate with their weight and cannot be sheared by the sliding line
• Components (e.g. sheet piling) may be sheared and thus operate with their shearing resistance
• Anchors with predefined inclinations, lengths and anchor forces serve as a back-up for the determination, if the anchor head is inside and the center of the press line is outside the sliding unit.

Any loads may influence the ground surface:

• Concentrated loads horizontal, vertical, single moments (immovable or movable loads)
• Distributed loads vertical (immovable or movable loads)
• Earthquake loads.

You may customize the lamella division. The finer the lamellas, the more precise the results.

There are different possibilities to manage the analysis approach:

Determination according to Krey-Bishop:

The friction circle may be predefined according to the center and the radius. Optionally, you may define a fixed point, through which the friction circle has to pass. (e.g. slope toes).

Various iteration possibilities are available for the determination of the minimal safety:

• Minimum search upwards from a predefined start point
• Minimum search upwards from a predefined radius
• Predefinition of a grid for the friction circle points
• Predefinition of a search range for the radius with a free dimension step each.

Determination according to Janbu:

The sliding line may consist of straight-line sectors, arcs of circles and tangents. The arcs may be defined as both fixed (by three points) and tangentially placed on adjacent straight-line sectors. The points between the different sectors be iterated following a line of selected inclination to determine the minimal safety.
