Buried Pipe

Dialog of soil type for underground pipe

Soil Stiffness

AutoPIPE allows you to calculate your buried pipes on the same model as the rest of your system, for both plastic and steel pipes. Apply the soil properties to your pipe is very easy, as AutoPIPE can model the stiffness of the soil given a depth according to ASCE (American Society of Civil Engineers), ALA (American Lifeline Alliance), and PRCI (Pipeline Research Council International) or use a model created by the user.

From the Analysis Set, you can also study cases with softer, harder or average soil properties in the same calculation, so you are covering the range of soil properties.

ASCE Recognition

AutoPIPE is the only pipe stress software recognized in by the American Society of Civil Engineers for buried pipe, so ASCE includes it in the bibliography of his Standards.

ASCE recognizes AutoPIPE as the pipe stress analysis solution

Seismic Waves

AutoPIPE Buried Model includes the pipe and its content mass, considering their density and therefore allowing many weight-related analyses like seismic, settlement, buoyancy, etc. Notice that other software change densities to zero for buried elements.

Seismic analysis can be performed in three ways:

  • Static Seismic Acceleration can be applied to the model.
  • Spectrum analysis can be performed.
  • Seismic waves travel faster in the pipe than through the ground, AutoPIPE can apply a Thermal Equivalent of the wave propagation which makes it the preferred solution for studying pipelines.

And no matter how long the line is, import the coordinates from Excel and have your model ready in minutes.

Sesimic Waves are transmitted trhough the soil and can affect your underground pipe
ASCE and ALA required stress calculations for pipelines

A.L.A. Pipelines Analysis

AutoPIPE can calculate all the loads indicated by the American Lifeline Alliance 2001 addenda 2005. Some of those analysis cannot be performed without considering the weight of the pipe, content and any additional weight, in fact only the stress due to thermal and pressure expansion can be analyzed.


In addition, AutoPIPE studies the ovalization or flattening of your pipe due to the weight of the ground and the loads applied on it, with which its thickness is verified.

And for flood areas, AutoPIPE also analyzes the liquefaction of the land, to calculate the supports or the extra weight to avoid the buoyancy of the pipe.
