The following buried pipe example problem is provided to illustrate the features of the modeler. This example should not be considered a guide for recommended underground piping design.

Consider the following example:

The following input listing represents the unburied model shown above.

Terminal nodes 100 and 1900 are above ground. Nodes 1250 and 1650 (on the sloped runs) mark the soil entry and exit points.

Using the Basic Soil Modeler dialog box, Soil Model Number 2 properties for a sandy soil is defined.

Elements 1250-1300 through 1600-1650 are buried using soil model number 2. Zone 1 meshing is indicated at the entry and exit points.

Clicking Convert on the Buried Pipe Modeler toolbar begins the conversion to a buried model.

The screen listing can also be printed.

The original unburied model is shown along with the buried model below. Restraints have been added around the elbows and along the straight runs.

Bi-linear restraints have been added to the buried model. The stiffness used is based upon the distance between nodes.

The first buried element, 1250-1251, has no density.

You can now analyze the buried job.
