Pile Types and Pile Cross-Section Properties

RSPile is undergoing some big and exciting changes to the way users define and design piles. The Pile Properties section of RSPile is getting an overhaul with the introduction of Pile Types. A pile type is a pile with a defined length and orientation. In this new workflow, users can define the properties of a pile type and then apply them to any pile just by selecting this pile type from the drop-down menu.

Within this pile type, users will also be able to define multiple sections that make up the pile type. These sections can consist of varying cross-sections whose properties can be defined using the Pile Cross-Section Properties option. Users can define these segments with different lengths, widths, reinforcements, and other aspects that come with a pile cross-section.

All of these changes are being introduced to give users more control over the way they define and analyze their piles. This new workflow will also allow users to more quickly apply properties to a pile allowing an overall quicker design process.

Bored Pile Analysis

RSPile: Bored Pile Analysis

The analysis of Bored piles differs from other options because of its focus on computing the Ultimate capacity of a pile in resisting applied load. The piles themselves differ as well. Unlike prefabricated piles, bored piles are formed by drilling a borehole for a reinforced concrete pile and pouring the concrete on site.

Bored piles are commonly used when building and reinforcing foundations of structures and are a great option for building near existing foundations because of the minimal vibrations caused by their installation. What’s more, they are thoroughly versatile option for when a project requires piles of varying lengths.

Needless to say, this analysis option is the ideal accompaniment to any urban geotechnical project requiring piles, and was, as a result, developed in accordance with the Federal Highway Administration (FHWA) and American Association of State Highway and Transportation (AASHT) standards.

Like with all pile options in RSPile, users have several cross-section design options for their reinforced concrete piles including circular, square and rectangular. Similarly, the soil properties options for Bored pile analysis include a comprehensive range of options, including some new soil types not previously offered in the program. The main soil conditions computations considered for bored piles though are the effects of soft soil conditions or scourable soils.

Carrying Capacity

With the addition of the Bored pile analysis option, also comes a refresh to the RSPile Project Settings. Users will notice a new Carrying Capacity category has been added, allowing you to consider piles for more than just Individual or Grouped Pile Analyses.

If that wasn’t enough, a new advanced analysis setting has been added allowing users to specify the Pile Depth Increment. This option allows users to specify the spacing between pile tip depths where the total capacity is computed for Bored Pile Analysis. Capacities, in this case, are computed starting at the defined pile head or ground surface (whichever elevation is less).

How to import an RSPile file into Slide2?

The installation of piles is one of the most common methods of slope stabilization in the industry. This makes the general pile analysis software RSPile a particularly useful addition to your slope stability suite. The RSPile program allows users to design and analyze numerous types of piles to meet the needs of their geotechnical project including driven piles, axial and laterally loaded piles, and grouped piles. In the case of slope stability analyses, RSPile automatically calculates the pile resistance by allowing the user to specify the range of sliding depths examined in the analysis and produce the corresponding pile resistance functions.

These pile resistance functions produced in RSPile are easily imported into the Slide2 program. Simply open the Define Support Properties dialog and select RSPile as your support type. From here you can launch RSPile and import the RSPile file directly into Slide2.

With one RSPile model file, a user can define the soil and pile properties for multiple piles of various embedment lengths and soil layer configurations.

For each intersected slip surface to a pile, Slide2 will use linear interpolation to determine the appropriate resultant pile resistance and compute the factor of safety.
