SoilModelEditor


Soil Model Editor is a software tool that assists in the creation of the soil models for all relevant SES software computation modules.

There are different soil type models:

Perfect Soil Model

Perfect soil is a special uniform soil where the earth is a metallic medium.

Uniform Soil

Uniform soil model consists of two semi-infinite regions of constant electrical properties: the air and a single soil layer, optionally containing one or more soil volumes of different resistivities.

Horizontal Soil Model

This option specifies the characteristics of a horizontally layered soil, optionally containing one or more soil volumes of different resistivities.

Cylindrical Horizontal Soil Model

Specifies a horizontal cylindrical soil model. The soil model consists of two regions delimited by a horizontal cylindrical interface.

Inclined Soil Model

Specifies a soil model with an inclined layer.

In order to describe an inclined soil, you must specify not only the electrical characteristics of each layer, but also the locations of the boundary or "interface" between the layers. The location of this boundary is specified in terms of

  • A reference point on the trace that the interface makes on the earth surface (point P in the figure).
  • The angle that the trace makes with the x-axis of the coordinate system selected for the conductor specifications (angle θ in the figure).
  • The inclination angle of the soil interface between the soil regions with respect to the earth surface (angle α in the figure).

Spherical Soil Model

Specifies the characteristics of a hemispherically layered soil. The soil model consists of three regions delimited by two concentric hemispherical interfaces.

Spheroidal Soil Model

Specifies the characteristics of a hemispheroidal soil model. A hemispheroidal soil model defines two soil regions delimited by one hemispheroidal interface. The intersection with the X-Y plane of the surface separating the two regions is a circle, while its intersection with any vertical plane is the lower half of an ellipse. The geometry of this surface is specified by the radius of the intersection circle with the X-Y plane and by the depth of the lowest point on the ellipse. Note that the depth is currently restricted to be smaller than the radius, i.e. the surface is technically an oblate spheroid.

Cylindrical Vertical Soil Model

Specifies a vertical cylindrical soil model. The soil model consists of two regions delimited by a vertical cylindrical interface.

Vertical Soil Model

Vertically layered soil model consists of a number of vertical soil layers with constant electrical properties. In order to describe a vertically-layered soil, one must specify not only the electrical characteristics of each layer, but also the locations of the boundaries or "interfaces" between the layers. These locations are specified in terms of:

  • X Reference, Y Reference: Coordinates of a point on the interface boundary (at z = 0) in meters or feet.
  • Trace Angle: The angle of the trace of interface between the soil layers on the earth surface with the positive direction of x -axis of the coordinate system (in degrees). Trace Angle: The angle of the trace of interface between the soil layers on the earth surface with the positive direction of x-axis of the coordinate system (in degrees).

Soil Volumes

The Volumes tab allows to specify one or several soil volumes of trapezoidal shape (formed by 6 surfaces and 8 vertices) embedded in Uniform or Horizontally-Layered native soil.
