Explanation

Soil Layers Method

Create a boring surface based on the defined boring data.

[Method]
Create a boring surface based on the defined boring data.
[Select Soil Layer]
Select the boring data and the soil layer to create the surface.
- Boring Data : Select the data set that was input in the boring data.
- Soil Layer : Select the boring surface to create.

This is enabled when the boring data and the soil layer are defined.

[Select Ground Surface]
Select the ground surface to use as a reference.
[Select Boundary Wire]
Select the boundary to create the boring surface.

If not selected, the boring surface is created around the boundary of the ground surface.

[Interpolation]
Determine the methodology to create the boring surface.

Kriging : This is a statistical method of minimizing the variance by obtaining the Best Linear Unbiased Estimator (BLUE) for an area where the boring data does not exist with the boring data value taken from a random space. This is generally most commonly used.
IDW(Inverse Distance Weighted) : This is a method to predict by placing a heavier weightage to values near the boring data in a random space.
Smooth Spline : This method connects the boring data values using a spline.
Delaunay Triangle : This method forms a triangular mesh and corrects from the closest point to the boring data value.

The UI values displayed are different for each method (Kriging / IDW(Inverse Distance Weighted) / Smooth Spline / Delaunay Triangle). Please refer to the reference materials attached below.

Soil Layers Method > Kriging Method

Create the boring surface using the Kriging method.

[Interpolation]
Select the interpolation method for the boring surface.
[Parameter]
- Kriging Type : Select the interpolation method for the data.
- Empirical Model : Variogram Modeling is used to define the regularity of the boring data that will be applied to Kriging. This is a method to estimate the closest theoretical curve.

Ordinary : The mean cannot be determined through Kriging, but the data is calibrated assuming that it is constant.
Universal : The data is calibrated by considereing the tendency of mean in normal Kriging.
Simple : The data is calibrated by assuming that the mean is constant using simple Kriging.

Linear : The points are interpolated as a straight line.
Spherical : The points are interpolated with linearly increasing tendency.
Exponential : The points are interpolated by conveging to a specific value.
Gaussian : The points are interpolated less in the vicinity and greater farther away.
Power : The points increase as the distance increases.
Hole-Effect : The points are interpolated by increasing at close range and by decreasing at a distance.
Wave : The points are interpolated in a waveform trend.
Rational Quadratic : The points are interpolated using a quadratic expression.
Circular : The points are interpolated using a trigonometric function.

[Auto Set Parameter]
Sets the parameter to Auto.

Click Auto Set Parameter to display the following graph.

Graphs are displayed according to the empirical mode and the sub options are as follows.

Lag Distance : Distance between pairs at which bariohram is calculated
Partial Sill : Convergence value
Slope : Slope
Exponent : Square root value
Range : Distance at which the slope of curve changes
Nugget : Graph constants

[Option]
These settings are applied when creating the boring surface.
- Extend Boundary : Extends the set boundary. Similar to the function of an offset.
- Resolution : Sets the resolution. Larger number results in higher resolution.
- Weight Factor : Sets the factor to exaggerate. Similar to a profile scale.

Soil Layers Method > IDW(Inverse Distance Weighted) Method

Creates the boring surface using the IDW method.

[Interpolation]
Select the interpolation method for the boring surface.
[Parameter]
Sets the parameter of the IDW method.
- Exponent : Sets the IDW. A larger exponent exaggerates the contour of the boring surface.
[Option]
These settings are applied when creating the boring surface.
- Extend Boundary : Extends the set boundary. Similar to the function of an offset.
- Edge Division : Setes the Edge Division.
- Face Division : Sets Face Division.
- Resolution : Set the precision. The higher the number, the more precise.
- Weight Factor : Set the factor to be exaggerated. Similar to profile scale.

Soil Layers Method > Smooth Spline Method
