How to Use the Software

The workflow in HelixPile V2026 is designed to be logical and efficient for practicing engineers. The following is a general guide to the process.

Creating a New Project and Defining Soil Profiles

After launching the software, create a new project. The first step involves defining the site’s subsurface conditions. HelixPile allows you to create multiple soil layers and assign appropriate parameters such as unit weight, friction angle, and undrained shear strength. You can import this data from a CPT log, which significantly speeds up the process .

Defining Pile Geometry and Helix Configuration

Next, define the helical pile geometry. This includes specifying:

• Shaft properties: Diameter, section modulus, and material (e.g., steel).

• Helix properties: Number of helices, diameter of each helix (typically increasing from top to bottom), pitch, and spacing between helices .

• Embedment depth: The total length of the pile shaft below the ground surface.

Conducting Axial and Lateral Capacity Analysis

Once the model is defined, proceed to the analysis. For axial capacity, HelixPile automatically calculates the ultimate capacity using both the Individual Plate Method and the Cylindrical Shear Method, and reports the governing lower value . For lateral analysis, the software uses advanced soil-structure interaction models (e.g., p-y curves) to evaluate the pile’s response to horizontal loads and moments, including trapezoidal loads .

Reviewing Results and Optimizing Design

After the analysis, review the results, which are presented in both graphical and tabular formats. You can view capacity curves, stress distribution, and failure envelopes. The software enables quick iteration, allowing you to alter the helix configuration and see how the optimized pile embedment depth changes . This optimization capability helps engineers balance structural integrity with cost-effectiveness.

Best Use Cases

HelixPile V2026 is applicable to a diverse range of geotechnical projects. Its primary use cases include:
